-3.1 LAMMPS input script :link(cmd_1),h4
-
-LAMMPS executes by reading commands from a input script (text file),
-one line at a time.  When the input script ends, LAMMPS exits.  Each
-command causes LAMMPS to take some action.  It may set an internal
-variable, read in a file, or run a simulation.  Most commands have
-default settings, which means you only need to use the command if you
-wish to change the default.
-
-In many cases, the ordering of commands in an input script is not
-important.  However the following rules apply:
-
-(1) LAMMPS does not read your entire input script and then perform a
-simulation with all the settings.  Rather, the input script is read
-one line at a time and each command takes effect when it is read.
-Thus this sequence of commands:
-
-timestep 0.5
-run      100
-run      100 :pre
-
-does something different than this sequence:
-
-run      100
-timestep 0.5
-run      100 :pre
-
-In the first case, the specified timestep (0.5 fmsec) is used for two
-simulations of 100 timesteps each.  In the 2nd case, the default
-timestep (1.0 fmsec) is used for the 1st 100 step simulation and a 0.5
-fmsec timestep is used for the 2nd one.
-
-(2) Some commands are only valid when they follow other commands.  For
-example you cannot set the temperature of a group of atoms until atoms
-have been defined and a group command is used to define which atoms
-belong to the group.
-
-(3) Sometimes command B will use values that can be set by command A.
-This means command A must precede command B in the input script if it
-is to have the desired effect.  For example, the
-"read_data"_read_data.html command initializes the system by setting
-up the simulation box and assigning atoms to processors.  If default
-values are not desired, the "processors"_processors.html and
-"boundary"_boundary.html commands need to be used before read_data to
-tell LAMMPS how to map processors to the simulation box.
-
-Many input script errors are detected by LAMMPS and an ERROR or
-WARNING message is printed.  "This section"_Section_errors.html gives
-more information on what errors mean.  The documentation for each
-command lists restrictions on how the command can be used.
-
-:line
-
-3.2 Parsing rules :link(cmd_2),h4
-
-Each non-blank line in the input script is treated as a command.
-LAMMPS commands are case sensitive.  Command names are lower-case, as
-are specified command arguments.  Upper case letters may be used in
-file names or user-chosen ID strings.
-
-Here is how each line in the input script is parsed by LAMMPS:
-
-(1) If the last printable character on the line is a "&" character,
-the command is assumed to continue on the next line.  The next line is
-concatenated to the previous line by removing the "&" character and
-line break.  This allows long commands to be continued across two or
-more lines.  See the discussion of triple quotes in (6) for how to
-continue a command across multiple line without using "&" characters.
-
-(2) All characters from the first "#" character onward are treated as
-comment and discarded.  See an exception in (6).  Note that a
-comment after a trailing "&" character will prevent the command from
-continuing on the next line.  Also note that for multi-line commands a
-single leading "#" will comment out the entire command.
-
-(3) The line is searched repeatedly for $ characters, which indicate
-variables that are replaced with a text string.  See an exception in
-(6).
-
-If the $ is followed by curly brackets, then the variable name is the
-text inside the curly brackets.  If no curly brackets follow the $,
-then the variable name is the single character immediately following
-the $.  Thus $\{myTemp\} and $x refer to variable names "myTemp" and
-"x".
-
-How the variable is converted to a text string depends on what style
-of variable it is; see the "variable"_variable.html doc page for details.
-It can be a variable that stores multiple text strings, and return one
-of them.  The returned text string can be multiple "words" (space
-separated) which will then be interpreted as multiple arguments in the
-input command.  The variable can also store a numeric formula which
-will be evaluated and its numeric result returned as a string.
-
-As a special case, if the $ is followed by parenthesis, then the text
-inside the parenthesis is treated as an "immediate" variable and
-evaluated as an "equal-style variable"_variable.html.  This is a way
-to use numeric formulas in an input script without having to assign
-them to variable names.  For example, these 3 input script lines:
-
-variable X equal (xlo+xhi)/2+sqrt(v_area)
-region 1 block $X 2 INF INF EDGE EDGE
-variable X delete :pre
-
-can be replaced by
-
-region 1 block $((xlo+xhi)/2+sqrt(v_area)) 2 INF INF EDGE EDGE :pre
-
-so that you do not have to define (or discard) a temporary variable X.
-
-Note that neither the curly-bracket or immediate form of variables can
-contain nested $ characters for other variables to substitute for.
-Thus you cannot do this:
-
-variable        a equal 2
-variable        b2 equal 4
-print           "B2 = $\{b$a\}" :pre
-
-Nor can you specify this $($x-1.0) for an immediate variable, but
-you could use $(v_x-1.0), since the latter is valid syntax for an
-"equal-style variable"_variable.html.
-
-See the "variable"_variable.html command for more details of how
-strings are assigned to variables and evaluated, and how they can be
-used in input script commands.
-
-(4) The line is broken into "words" separated by whitespace (tabs,
-spaces).  Note that words can thus contain letters, digits,
-underscores, or punctuation characters.
-
-(5) The first word is the command name.  All successive words in the
-line are arguments.
-
-(6) If you want text with spaces to be treated as a single argument,
-it can be enclosed in either single or double or triple quotes.  A
-long single argument enclosed in single or double quotes can span
-multiple lines if the "&" character is used, as described above.  When
-the lines are concatenated together (and the "&" characters and line
-breaks removed), the text will become a single line.  If you want
-multiple lines of an argument to retain their line breaks, the text
-can be enclosed in triple quotes, in which case "&" characters are not
-needed.  For example:
-
-print "Volume = $v"
-print 'Volume = $v'
-if "$\{steps\} > 1000" then quit
-variable a string "red green blue &
-                   purple orange cyan"
-print """
-System volume = $v
-System temperature = $t
-""" :pre
-
-In each case, the single, double, or triple quotes are removed when
-the single argument they enclose is stored internally.
-
-See the "dump modify format"_dump_modify.html, "print"_print.html,
-"if"_if.html, and "python"_python.html commands for examples.
-
-A "#" or "$" character that is between quotes will not be treated as a
-comment indicator in (2) or substituted for as a variable in (3).
-
-NOTE: If the argument is itself a command that requires a quoted
-argument (e.g. using a "print"_print.html command as part of an
-"if"_if.html or "run every"_run.html command), then single, double, or
-triple quotes can be nested in the usual manner.  See the doc pages
-for those commands for examples.  Only one of level of nesting is
-allowed, but that should be sufficient for most use cases.

-3.3 Input script structure :h3,link(cmd_3)
-
-This section describes the structure of a typical LAMMPS input script.
-The "examples" directory in the LAMMPS distribution contains many
-sample input scripts; the corresponding problems are discussed in
-"Section 7"_Section_example.html, and animated on the "LAMMPS
-WWW Site"_lws.
-
-A LAMMPS input script typically has 4 parts:
-
-Initialization
-Atom definition
-Settings
-Run a simulation :ol
-
-The last 2 parts can be repeated as many times as desired.  I.e. run a
-simulation, change some settings, run some more, etc.  Each of the 4
-parts is now described in more detail.  Remember that almost all the
-commands need only be used if a non-default value is desired.
-
-(1) Initialization
-
-Set parameters that need to be defined before atoms are created or
-read-in from a file.
-
-The relevant commands are "units"_units.html,
-"dimension"_dimension.html, "newton"_newton.html,
-"processors"_processors.html, "boundary"_boundary.html,
-"atom_style"_atom_style.html, "atom_modify"_atom_modify.html.
-
-If force-field parameters appear in the files that will be read, these
-commands tell LAMMPS what kinds of force fields are being used:
-"pair_style"_pair_style.html, "bond_style"_bond_style.html,
-"angle_style"_angle_style.html, "dihedral_style"_dihedral_style.html,
-"improper_style"_improper_style.html.
-
-(2) Atom definition
-
-There are 3 ways to define atoms in LAMMPS.  Read them in from a data
-or restart file via the "read_data"_read_data.html or
-"read_restart"_read_restart.html commands.  These files can contain
-molecular topology information.  Or create atoms on a lattice (with no
-molecular topology), using these commands: "lattice"_lattice.html,
-"region"_region.html, "create_box"_create_box.html,
-"create_atoms"_create_atoms.html.  The entire set of atoms can be
-duplicated to make a larger simulation using the
-"replicate"_replicate.html command.
-
-(3) Settings
-
-Once atoms and molecular topology are defined, a variety of settings
-can be specified: force field coefficients, simulation parameters,
-output options, etc.
-
-Force field coefficients are set by these commands (they can also be
-set in the read-in files): "pair_coeff"_pair_coeff.html,
-"bond_coeff"_bond_coeff.html, "angle_coeff"_angle_coeff.html,
-"dihedral_coeff"_dihedral_coeff.html,
-"improper_coeff"_improper_coeff.html,
-"kspace_style"_kspace_style.html, "dielectric"_dielectric.html,
-"special_bonds"_special_bonds.html.
-
-Various simulation parameters are set by these commands:
-"neighbor"_neighbor.html, "neigh_modify"_neigh_modify.html,
-"group"_group.html, "timestep"_timestep.html,
-"reset_timestep"_reset_timestep.html, "run_style"_run_style.html,
-"min_style"_min_style.html, "min_modify"_min_modify.html.
-
-Fixes impose a variety of boundary conditions, time integration, and
-diagnostic options.  The "fix"_fix.html command comes in many flavors.
-
-Various computations can be specified for execution during a
-simulation using the "compute"_compute.html,
-"compute_modify"_compute_modify.html, and "variable"_variable.html
-commands.
-
-Output options are set by the "thermo"_thermo.html, "dump"_dump.html,
-and "restart"_restart.html commands.
-
-(4) Run a simulation
-
-A molecular dynamics simulation is run using the "run"_run.html
-command.  Energy minimization (molecular statics) is performed using
-the "minimize"_minimize.html command.  A parallel tempering
-(replica-exchange) simulation can be run using the
-"temper"_temper.html command.

-next section also includes (long) lists of style options for entries
-that appear in the following categories as a single command (fix,
-compute, pair, etc).  Commands that are added by user packages are not

-compute displace/atom command :h3
-
-[Syntax:]
-
-compute ID group-ID displace/atom :pre
-
-ID, group-ID are documented in "compute"_compute.html command :ulb,l
-displace/atom = style name of this compute command :l
-zero or more keyword/arg pairs may be appended :l
-keyword = {refresh} :l
-  {replace} arg = per-atom variable ID :pre
-:ule
-
-[Examples:]
-
-compute 1 all displace/atom
-compute 1 all displace/atom refresh myVar :pre
-
-[Description:]
-
-Define a computation that calculates the current displacement of each
-atom in the group from its original (reference) coordinates, including
-all effects due to atoms passing thru periodic boundaries.
-
-A vector of four quantities per atom is calculated by this compute.
-The first 3 elements of the vector are the dx,dy,dz displacements.
-The 4th component is the total displacement, i.e. sqrt(dx*dx + dy*dy +
-dz*dz).
-
-The displacement of an atom is from its original position at the time
-the compute command was issued.  The value of the displacement will be
-0.0 for atoms not in the specified compute group.
-
-NOTE: Initial coordinates are stored in "unwrapped" form, by using the
-image flags associated with each atom.  See the "dump
-custom"_dump.html command for a discussion of "unwrapped" coordinates.
-See the Atoms section of the "read_data"_read_data.html command for a
-discussion of image flags and how they are set for each atom.  You can
-reset the image flags (e.g. to 0) before invoking this compute by
-using the "set image"_set.html command.
-
-NOTE: If you want the quantities calculated by this compute to be
-continuous when running from a "restart file"_read_restart.html, then
-you should use the same ID for this compute, as in the original run.
-This is so that the fix this compute creates to store per-atom
-quantities will also have the same ID, and thus be initialized
-correctly with time=0 atom coordinates from the restart file.
-
-:line
-
-The {refresh} option can be used in conjuction with the "dump_modify
-refresh" command to generate incremental dump files.
-
-The definition and motivation of an incremental dump file is as
-follows.  Instead of outputting all atoms at each snapshot (with some
-associated values), you may only wish to output the subset of atoms
-with a value that has changed in some way compared to the value the
-last time that atom was output.  In some scenarios this can result in
-a dramatically smaller dump file.  If desired, by post-processing the
-sequence of snapshots, the values for all atoms at all timesteps can
-be inferred.
-
-A concrete example using this compute, is a simulation of atom
-diffusion in a solid, represented as atoms on a lattice.  Diffusive
-hops are rare.  Imagine that when a hop occurs an atom moves more than
-a distance {Dhop}.  For any snapshot we only want to output atoms that
-have hopped since the last snapshot.  This can be accomplished with
-something like the following commands:
-
-write_dump      all custom tmp.dump id type x y z    # see comment below :pre
-
-variable        Dhop equal 0.6
-variable        check atom "c_dsp[4] > v_Dhop"
-compute         dsp all displace/atom refresh check
-dump            1 all custom 100 tmp.dump id type x y z
-dump_modify     1 append yes thresh c_dsp[4] > ${Dhop} &
-                refresh c_dsp delay 100 :pre
-
-The "dump_modify thresh"_dump_modify.html command will only ouptut
-atoms that have displaced more than 0.6 Angstroms on each snapshot
-(assuming metal units).  The dump_modify {refresh} option triggers a
-call to this compute at the end of every dump.
-
-The {refresh} argument for this compute is the ID of an "atom-style
-variable"_variable.html which calculates a Boolean value (0 or 1)
-based on the same criterion used by dump_modify thresh.  This compute
-evaluates the atom-style variable.  For each atom that returns 1
-(true), the original (reference) coordinates of the atom (stored by
-this compute) are updated.
-
-The effect of these commands is that a particular atom will only be
-output in the dump file on the snapshot after it makes a diffusive
-hop.  It will not be output again until it makes another hop.
-
-Note that in the first snapshot of a subsequent run, no atoms will be
-typically be output.  That is because the initial displacement for all
-atoms is 0.0.  If an initial dump snapshot is desired, containing the
-initial reference positions of all atoms, one way to do this is
-illustrated above.  An initial write_dump command can be used before
-the first run.  It will contain the positions of all the atoms,
-Options in the "dump_modify"_dump_modify.html command above will
-append new output to that same file and delay the output until a later
-timestep.  The {delay} setting avoids a second time = 0 snapshot which
-would be empty.
-
-:line
-
-[Output info:]
-
-This compute calculates a per-atom array with 4 columns, which can be
-accessed by indices 1-4 by any command that uses per-atom values from
-a compute as input.  See "Section
-6.15"_Section_howto.html#howto_15 for an overview of LAMMPS output
-options.
-
-The per-atom array values will be in distance "units"_units.html.
-
-This compute supports the {refresh} option as explained above, for use
-in conjunction with "dump_modify refresh"_dump_modify.html to generate
-incremental dump files.

-[Description:]
-
-This command creates atoms (or molecules) on a lattice, or a single
-atom (or molecule), or a random collection of atoms (or molecules), as
-an alternative to reading in their coordinates explicitly via a
-"read_data"_read_data.html or "read_restart"_read_restart.html
-command.  A simulation box must already exist, which is typically
-created via the "create_box"_create_box.html command.  Before using
-this command, a lattice must also be defined using the
-"lattice"_lattice.html command, unless you specify the {single} style
-with units = box or the {random} style.  For the remainder of this doc
-page, a created atom or molecule is referred to as a "particle".
-
-If created particles are individual atoms, they are assigned the
-specified atom {type}, though this can be altered via the {basis}
-keyword as discussed below.  If molecules are being created, the type
-of each atom in the created molecule is specified in the file read by
-the "molecule"_molecule.html command, and those values are added to
-the specified atom {type}.  E.g. if {type} = 2, and the file specifies
-atom types 1,2,3, then each created molecule will have atom types
-3,4,5.
-
-For the {box} style, the create_atoms command fills the entire
-simulation box with particles on the lattice.  If your simulation box
-is periodic, you should insure its size is a multiple of the lattice
-spacings, to avoid unwanted atom overlaps at the box boundaries.  If
-your box is periodic and a multiple of the lattice spacing in a
-particular dimension, LAMMPS is careful to put exactly one particle at
-the boundary (on either side of the box), not zero or two.
-
-For the {region} style, a geometric volume is filled with particles on
-the lattice.  This volume what is inside the simulation box and is
-also consistent with the region volume.  See the "region"_region.html
-command for details.  Note that a region can be specified so that its
-"volume" is either inside or outside a geometric boundary.  Also note
-that if your region is the same size as a periodic simulation box (in
-some dimension), LAMMPS does not implement the same logic described
-above as for the {box} style, to insure exactly one particle at
-periodic boundaries.  if this is what you desire, you should either
-use the {box} style, or tweak the region size to get precisely the
-particles you want.
-
-For the {single} style, a single particle is added to the system at
-the specified coordinates.  This can be useful for debugging purposes
-or to create a tiny system with a handful of particles at specified
-positions.
-
-For the {random} style, N particles are added to the system at
-randomly generated coordinates, which can be useful for generating an
-amorphous system.  The particles are created one by one using the
-specified random number {seed}, resulting in the same set of particles
-coordinates, independent of how many processors are being used in the
-simulation.  If the {region-ID} argument is specified as NULL, then
-the created particles will be anywhere in the simulation box.  If a
-{region-ID} is specified, a geometric volume is filled which is both
-inside the simulation box and is also consistent with the region
-volume.  See the "region"_region.html command for details.  Note that
-a region can be specified so that its "volume" is either inside or
-outside a geometric boundary.
-
-NOTE: Particles generated by the {random} style will typically be
-highly overlapped which will cause many interatomic potentials to
-compute large energies and forces.  Thus you should either perform an
-"energy minimization"_minimize.html or run dynamics with "fix
-nve/limit"_fix_nve_limit.html to equilibrate such a system, before
-running normal dynamics.
-
-Note that this command adds particles to those that already exist.
-This means it can be used to add particles to a system previously read
-in from a data or restart file.  Or the create_atoms command can be
-used multiple times, to add multiple sets of particles to the
-simulation.  For example, grain boundaries can be created, by
-interleaving create_atoms with "lattice"_lattice.html commands
-specifying different orientations.  By using the create_atoms command
-in conjunction with the "delete_atoms"_delete_atoms.html command,
-reasonably complex geometries can be created, or a protein can be
-solvated with a surrounding box of water molecules.
-
-In all these cases, care should be taken to insure that new atoms do
-not overlap existing atoms inappropriately, especially if molecules
-are being added.  The "delete_atoms"_delete_atoms.html command can be
-used to remove overlapping atoms or molecules.
-
-NOTE: You cannot use any of the styles explained above to create atoms
-that are outside the simulation box; they will just be ignored by
-LAMMPS.  This is true even if you are using shrink-wrapped box
-boundaries, as specified by the "boundary"_boundary.html command.
-However, you can first use the "change_box"_change_box.html command to
-temporarily expand the box, then add atoms via create_atoms, then
-finally use change_box command again if needed to re-shrink-wrap the
-new atoms.  See the "change_box"_change_box.html doc page for an
-example of how to do this, using the create_atoms {single} style to
-insert a new atom outside the current simulation box.
-
-:line
-
-Individual atoms are inserted by this command, unless the {mol}
-keyword is used.  It specifies a {template-ID} previously defined
-using the "molecule"_molecule.html command, which reads a file that
-defines the molecule.  The coordinates, atom types, charges, etc, as
-well as any bond/angle/etc and special neighbor information for the
-molecule can be specified in the molecule file.  See the
-"molecule"_molecule.html command for details.  The only settings
-required to be in this file are the coordinates and types of atoms in
-the molecule.
-
-Using a lattice to add molecules, e.g. via the {box} or {region} or
-{single} styles, is exactly the same as adding atoms on lattice
-points, except that entire molecules are added at each point, i.e. on
-the point defined by each basis atom in the unit cell as it tiles the
-simulation box or region.  This is done by placing the geometric
-center of the molecule at the lattice point, and giving the molecule a
-random orientation about the point.  The random {seed} specified with
-the {mol} keyword is used for this operation, and the random numbers
-generated by each processor are different.  This means the coordinates
-of individual atoms (in the molecules) will be different when running
-on different numbers of processors, unlike when atoms are being
-created in parallel.
-
-Also note that because of the random rotations, it may be important to
-use a lattice with a large enough spacing that adjacent molecules will
-not overlap, regardless of their relative orientations.
-
-NOTE: If the "create_box"_create_box.html command is used to create
-the simulation box, followed by the create_atoms command with its
-{mol} option for adding molecules, then you typically need to use the
-optional keywords allowed by the "create_box"_create_box.html command
-for extra bonds (angles,etc) or extra special neighbors.  This is
-because by default, the "create_box"_create_box.html command sets up a
-non-molecular system which doesn't allow molecules to be added.
-
-:line
-
-This is the meaning of the other allowed keywords.
-
-The {basis} keyword is only used when atoms (not molecules) are being
-created.  It specifies an atom type that will be assigned to specific
-basis atoms as they are created.  See the "lattice"_lattice.html
-command for specifics on how basis atoms are defined for the unit cell
-of the lattice.  By default, all created atoms are assigned the
-argument {type} as their atom type.
-
-The {remap} keyword only applies to the {single} style.  If it is set
-to {yes}, then if the specified position is outside the simulation
-box, it will mapped back into the box, assuming the relevant
-dimensions are periodic.  If it is set to {no}, no remapping is done
-and no particle is created if its position is outside the box.
-
-The {var} and {set} keywords can be used together to provide a
-criterion for accepting or rejecting the addition of an individual
-atom, based on its coordinates.  The {name} specified for the {var}
-keyword is the name of an "equal-style variable"_variable.html which
-should evaluate to a zero or non-zero value based on one or two or
-three variables which will store the x, y, or z coordinates of an atom
-(one variable per coordinate).  If used, these other variables must be
-"internal-style variables"_variable.html defined in the input script;
-their initial numeric value can be anything.  They must be
-internal-style variables, because this command resets their values
-directly.  The {set} keyword is used to identify the names of these
-other variables, one variable for the x-coordinate of a created atom,
-one for y, and one for z.
-
-When an atom is created, its x,y,z coordinates become the values for
-any {set} variable that is defined.  The {var} variable is then
-evaluated.  If the returned value is 0.0, the atom is not created.  If
-it is non-zero, the atom is created.
-
-As an example, these commands can be used in a 2d simulation, to
-create a sinusoidal surface.  Note that the surface is "rough" due to
-individual lattice points being "above" or "below" the mathematical
-expression for the sinusoidal curve.  If a finer lattice were used,
-the sinusoid would appear to be "smoother".  Also note the use of the
-"xlat" and "ylat" "thermo_style"_thermo_style.html keywords which
-converts lattice spacings to distance.  Click on the image for a
-larger version.

-
-The {rotate} keyword can only be used with the {single} style and
-when adding a single molecule. It allows to specify the orientation
-at which the molecule is inserted.  The axis of rotation is
-determined by the rotation vector (Rx,Ry,Rz) that goes through the
-insertion point.  The specified {theta} determines the angle of
-rotation around that axis.  Note that the direction of rotation for
-the atoms around the rotation axis is consistent with the right-hand
-rule: if your right-hand's thumb points along {R}, then your fingers
-wrap around the axis in the direction of rotation.
-
-The {units} keyword determines the meaning of the distance units used
-to specify the coordinates of the one particle created by the {single}
-style.  A {box} value selects standard distance units as defined by
-the "units"_units.html command, e.g. Angstroms for units = real or
-metal.  A {lattice} value means the distance units are in lattice
-spacings.

-
-Atom IDs are assigned to created atoms in the following way.  The
-collection of created atoms are assigned consecutive IDs that start
-immediately following the largest atom ID existing before the
-create_atoms command was invoked.  This is done by the processor's
-communicating the number of atoms they each own, the first processor
-numbering its atoms from 1 to N1, the second processor from N1+1 to
-N2, etc.  Where N1 = number of atoms owned by the first processor, N2
-= number owned by the second processor, etc.  Thus when the same
-simulation is performed on different numbers of processors, there is
-no guarantee a particular created atom will be assigned the same ID in
-both simulations.  If molecules are being created, molecule IDs are
-assigned to created molecules in a similar fashion.
-
-Aside from their ID, atom type, and xyz position, other properties of
-created atoms are set to default values, depending on which quantities
-are defined by the chosen "atom style"_atom_style.html.  See the "atom
-style"_atom_style.html command for more details.  See the
-"set"_set.html and "velocity"_velocity.html commands for info on how
-to change these values.

-charge = 0.0
-dipole moment magnitude = 0.0
-diameter = 1.0
-shape = 0.0 0.0 0.0
-density = 1.0
-volume = 1.0
-velocity = 0.0 0.0 0.0

-angular momentum = 0.0 0.0 0.0
-quaternion = (1,0,0,0)
-bonds, angles, dihedrals, impropers = none :ul
-
-If molecules are being created, these defaults can be overridden by
-values specified in the file read by the "molecule"_molecule.html
-command.  E.g. the file typically defines bonds (angles,etc) between
-atoms in the molecule, and can optionally define charges on each atom.
-
-Note that the {sphere} atom style sets the default particle diameter
-to 1.0 as well as the density.  This means the mass for the particle
-is not 1.0, but is PI/6 * diameter^3 = 0.5236.
-
-Note that the {ellipsoid} atom style sets the default particle shape
-to (0.0 0.0 0.0) and the density to 1.0 which means it is a point
-particle, not an ellipsoid, and has a mass of 1.0.
-
-Note that the {peri} style sets the default volume and density to 1.0
-and thus also set the mass for the particle to 1.0.
-
-The "set"_set.html command can be used to override many of these
-default settings.

-
-[Description:]
-
-Delete the specified atoms.  This command can be used to carve out
-voids from a block of material or to delete created atoms that are too
-close to each other (e.g. at a grain boundary).
-
-For style {group}, all atoms belonging to the group are deleted.
-
-For style {region}, all atoms in the region volume are deleted.
-Additional atoms can be deleted if they are in a molecule for which
-one or more atoms were deleted within the region; see the {mol}
-keyword discussion below.
-
-For style {overlap} pairs of atoms whose distance of separation is
-within the specified cutoff distance are searched for, and one of the
-2 atoms is deleted.  Only pairs where one of the two atoms is in the
-first group specified and the other atom is in the second group are
-considered.  The atom that is in the first group is the one that is
-deleted.
-
-Note that it is OK for the two group IDs to be the same (e.g. group
-{all}), or for some atoms to be members of both groups.  In these
-cases, either atom in the pair may be deleted.  Also note that if
-there are atoms which are members of both groups, the only guarantee
-is that at the end of the deletion operation, enough deletions will
-have occurred that no atom pairs within the cutoff will remain
-(subject to the group restriction).  There is no guarantee that the
-minimum number of atoms will be deleted, or that the same atoms will
-be deleted when running on different numbers of processors.
-
-For style {porosity} a specified {fraction} of atoms are deleted
-within the specified region.  For example, if fraction is 0.1, then
-10% of the atoms will be deleted.  The atoms to delete are chosen
-randomly.  There is no guarantee that the exact fraction of atoms will
-be deleted, or that the same atoms will be deleted when running on
-different numbers of processors.
-
-If the {compress} keyword is set to {yes}, then after atoms are
-deleted, then atom IDs are re-assigned so that they run from 1 to the
-number of atoms in the system.  Note that this is not done for
-molecular systems (see the "atom_style"_atom_style.html command),
-regardless of the {compress} setting, since it would foul up the bond
-connectivity that has already been assigned.  However, the
-"reset_ids"_reset_ids.html command can be used after this command to
-accomplish the same thing.
-
-Note that the re-assignement of IDs is not really a compression, where
-gaps in atom IDs are removed by decrementing atom IDs that are larger.
-Instead the IDs for all atoms are erased, and new IDs are assigned so
-that the atoms owned by individual processors have consecutive IDs, as
-the "create_atoms"_create_atoms.html command explains.
-
-A molecular system with fixed bonds, angles, dihedrals, or improper
-interactions, is one where the topology of the interactions is
-typically defined in the data file read by the
-"read_data"_read_data.html command, and where the interactions
-themselves are defined with the "bond_style"_bond_style.html,
-"angle_style"_angle_style.html, etc commands.  If you delete atoms
-from such a system, you must be careful not to end up with bonded
-interactions that are stored by remaining atoms but which include
-deleted atoms.  This will cause LAMMPS to generate a "missing atoms"
-error when the bonded interaction is computed.  The {bond} and {mol}
-keywords offer two ways to do that.
-
-It the {bond} keyword is set to {yes} then any bond or angle or
-dihedral or improper interaction that includes a deleted atom is also
-removed from the lists of such interactions stored by non-deleted
-atoms.  Note that simply deleting interactions due to dangling bonds
-(e.g. at a surface) may result in a inaccurate or invalid model for
-the remaining atoms.
-
-It the {mol} keyword is set to {yes}, then for every atom that is
-deleted, all other atoms in the same molecule (with the same molecule
-ID) will also be deleted.  This is not done for atoms with molecule ID
-= 0, since such an ID is assumed to flag isolated atoms that are not
-part of molecules.
-
-NOTE: The molecule deletion operation in invoked after all individual
-atoms have been deleted using the rules described above for each
-style.  This means additional atoms may be deleted that are not in the
-group or region, that are not required by the overlap cutoff
-criterion, or that will create a higher fraction of porosity than was
-requested.
-
-[Restrictions:]
-
-The {overlap} styles requires inter-processor communication to acquire
-ghost atoms and build a neighbor list.  This means that your system
-must be ready to perform a simulation before using this command (force
-fields setup, atom masses set, etc).  Since a neighbor list is used to
-find overlapping atom pairs, it also means that you must define a
-"pair style"_pair_style.html with the minimum force cutoff distance
-between any pair of atoms types (plus the "neighbor"_neighbor.html
-skin) >= the specified overlap cutoff.
-
-If the "special_bonds"_special_bonds.html command is used with a
-setting of 0, then a pair of bonded atoms (1-2, 1-3, or 1-4) will not
-appear in the neighbor list, and thus will not be considered for
-deletion by the {overlap} styles.  You probably don't want to be
-deleting one atom in a bonded pair anyway.
-
-The {bond yes} option cannot be used with molecular systems defined
-using molecule template files via the "molecule"_molecule.html and
-"atom_style template"_atom_style.html commands.
-
-[Related commands:]
-
-"create_atoms"_create_atoms.html, "reset_ids"_reset_ids.html
-
-[Default:]
-
-The option defaults are compress = yes, bond = no, mol = no.

-[Description:]
-
-Dump a snapshot of atom quantities to one or more files every N
-timesteps in one of several styles.  The {image} and {movie} styles are
-the exception: the {image} style renders a JPG, PNG, or PPM image file
-of the atom configuration every N timesteps while the {movie} style
-combines and compresses them into a movie file; both are discussed in
-detail on the "dump image"_dump_image.html doc page.  The timesteps on
-which dump output is written can also be controlled by a variable.
-See the "dump_modify every"_dump_modify.html command.
-
-Only information for atoms in the specified group is dumped.  The
-"dump_modify thresh and region and refresh"_dump_modify.html commands
-can also alter what atoms are included.  Not all styles support all
-these options; see details on the "dump_modify"_dump_modify.html doc
-page.
-
-As described below, the filename determines the kind of output (text
-or binary or gzipped, one big file or one per timestep, one big file
-or multiple smaller files).
-
-NOTE: Because periodic boundary conditions are enforced only on
-timesteps when neighbor lists are rebuilt, the coordinates of an atom
-written to a dump file may be slightly outside the simulation box.
-Re-neighbor timesteps will not typically coincide with the timesteps
-dump snapshots are written.  See the "dump_modify
-pbc"_dump_modify.html command if you with to force coordinates to be
-strictly inside the simulation box.
-
-NOTE: Unless the "dump_modify sort"_dump_modify.html option is
-invoked, the lines of atom information written to dump files
-(typically one line per atom) will be in an indeterminate order for
-each snapshot.  This is even true when running on a single processor,
-if the "atom_modify sort"_atom_modify.html option is on, which it is
-by default.  In this case atoms are re-ordered periodically during a
-simulation, due to spatial sorting.  It is also true when running in
-parallel, because data for a single snapshot is collected from
-multiple processors, each of which owns a subset of the atoms.
-
-For the {atom}, {custom}, {cfg}, and {local} styles, sorting is off by
-default.  For the {dcd}, {xtc}, {xyz}, and {molfile} styles, sorting by
-atom ID is on by default. See the "dump_modify"_dump_modify.html doc
-page for details.
-
-The {atom/gz}, {cfg/gz}, {custom/gz}, and {xyz/gz} styles are identical
-in command syntax to the corresponding styles without "gz", however,
-they generate compressed files using the zlib library. Thus the filename
-suffix ".gz" is mandatory. This is an alternative approach to writing
-compressed files via a pipe, as done by the regular dump styles, which
-may be required on clusters where the interface to the high-speed network
-disallows using the fork() library call (which is needed for a pipe).
-For the remainder of this doc page, you should thus consider the {atom}
-and {atom/gz} styles (etc) to be inter-changeable, with the exception
-of the required filename suffix.
-
-As explained below, the {atom/mpiio}, {cfg/mpiio}, {custom/mpiio}, and
-{xyz/mpiio} styles are identical in command syntax and in the format
-of the dump files they create, to the corresponding styles without
-"mpiio", except the single dump file they produce is written in
-parallel via the MPI-IO library.  For the remainder of this doc page,
-you should thus consider the {atom} and {atom/mpiio} styles (etc) to
-be inter-changeable.  The one exception is how the filename is
-specified for the MPI-IO styles, as explained below.
-
-The precision of values output to text-based dump files can be
-controlled by the "dump_modify format"_dump_modify.html command and
-its options.
-
-:line
-
-The {style} keyword determines what atom quantities are written to the
-file and in what format.  Settings made via the
-"dump_modify"_dump_modify.html command can also alter the format of
-individual values and the file itself.
-
-The {atom}, {local}, and {custom} styles create files in a simple text
-format that is self-explanatory when viewing a dump file.  Many of the
-LAMMPS "post-processing tools"_Section_tools.html, including
-"Pizza.py"_http://www.sandia.gov/~sjplimp/pizza.html, work with this
-format, as does the "rerun"_rerun.html command.
-
-For post-processing purposes the {atom}, {local}, and {custom} text
-files are self-describing in the following sense.
-
-The dimensions of the simulation box are included in each snapshot.
-For an orthogonal simulation box this information is is formatted as:
-
-ITEM: BOX BOUNDS xx yy zz
-xlo xhi
-ylo yhi
-zlo zhi :pre
-
-where xlo,xhi are the maximum extents of the simulation box in the
-x-dimension, and similarly for y and z.  The "xx yy zz" represent 6
-characters that encode the style of boundary for each of the 6
-simulation box boundaries (xlo,xhi and ylo,yhi and zlo,zhi).  Each of
-the 6 characters is either p = periodic, f = fixed, s = shrink wrap,
-or m = shrink wrapped with a minimum value.  See the
-"boundary"_boundary.html command for details.
-
-For triclinic simulation boxes (non-orthogonal), an orthogonal
-bounding box which encloses the triclinic simulation box is output,
-along with the 3 tilt factors (xy, xz, yz) of the triclinic box,
-formatted as follows:
-
-ITEM: BOX BOUNDS xy xz yz xx yy zz
-xlo_bound xhi_bound xy
-ylo_bound yhi_bound xz
-zlo_bound zhi_bound yz :pre
-
-The presence of the text "xy xz yz" in the ITEM line indicates that
-the 3 tilt factors will be included on each of the 3 following lines.
-This bounding box is convenient for many visualization programs.  The
-meaning of the 6 character flags for "xx yy zz" is the same as above.
-
-Note that the first two numbers on each line are now xlo_bound instead
-of xlo, etc, since they represent a bounding box.  See "this
-section"_Section_howto.html#howto_12 of the doc pages for a geometric
-description of triclinic boxes, as defined by LAMMPS, simple formulas
-for how the 6 bounding box extents (xlo_bound,xhi_bound,etc) are
-calculated from the triclinic parameters, and how to transform those
-parameters to and from other commonly used triclinic representations.
-
-The "ITEM: ATOMS" line in each snapshot lists column descriptors for
-the per-atom lines that follow.  For example, the descriptors would be
-"id type xs ys zs" for the default {atom} style, and would be the atom
-attributes you specify in the dump command for the {custom} style.
-
-For style {atom}, atom coordinates are written to the file, along with
-the atom ID and atom type.  By default, atom coords are written in a
-scaled format (from 0 to 1).  I.e. an x value of 0.25 means the atom
-is at a location 1/4 of the distance from xlo to xhi of the box
-boundaries.  The format can be changed to unscaled coords via the
-"dump_modify"_dump_modify.html settings.  Image flags can also be
-added for each atom via dump_modify.
-
-Style {custom} allows you to specify a list of atom attributes to be
-written to the dump file for each atom.  Possible attributes are
-listed above and will appear in the order specified.  You cannot
-specify a quantity that is not defined for a particular simulation -
-such as {q} for atom style {bond}, since that atom style doesn't
-assign charges.  Dumps occur at the very end of a timestep, so atom
-attributes will include effects due to fixes that are applied during
-the timestep.  An explanation of the possible dump custom attributes
-is given below.
-
-For style {local}, local output generated by "computes"_compute.html
-and "fixes"_fix.html is used to generate lines of output that is
-written to the dump file.  This local data is typically calculated by
-each processor based on the atoms it owns, but there may be zero or
-more entities per atom, e.g. a list of bond distances.  An explanation
-of the possible dump local attributes is given below.  Note that by
-using input from the "compute
-property/local"_compute_property_local.html command with dump local,
-it is possible to generate information on bonds, angles, etc that can
-be cut and pasted directly into a data file read by the
-"read_data"_read_data.html command.
-
-Style {cfg} has the same command syntax as style {custom} and writes
-extended CFG format files, as used by the
-"AtomEye"_http://mt.seas.upenn.edu/Archive/Graphics/A visualization
-package.  Since the extended CFG format uses a single snapshot of the
-system per file, a wildcard "*" must be included in the filename, as
-discussed below.  The list of atom attributes for style {cfg} must
-begin with either "mass type xs ys zs" or "mass type xsu ysu zsu"
-since these quantities are needed to write the CFG files in the
-appropriate format (though the "mass" and "type" fields do not appear
-explicitly in the file).  Any remaining attributes will be stored as
-"auxiliary properties" in the CFG files.  Note that you will typically
-want to use the "dump_modify element"_dump_modify.html command with
-CFG-formatted files, to associate element names with atom types, so
-that AtomEye can render atoms appropriately. When unwrapped
-coordinates {xsu}, {ysu}, and {zsu} are requested, the nominal AtomEye
-periodic cell dimensions are expanded by a large factor UNWRAPEXPAND =
-10.0, which ensures atoms that are displayed correctly for up to
-UNWRAPEXPAND/2 periodic boundary crossings in any direction.  Beyond
-this, AtomEye will rewrap the unwrapped coordinates.  The expansion
-causes the atoms to be drawn farther away from the viewer, but it is
-easy to zoom the atoms closer, and the interatomic distances are
-unaffected.
-
-The {dcd} style writes DCD files, a standard atomic trajectory format
-used by the CHARMM, NAMD, and XPlor molecular dynamics packages.  DCD
-files are binary and thus may not be portable to different machines.
-The number of atoms per snapshot cannot change with the {dcd} style.
-The {unwrap} option of the "dump_modify"_dump_modify.html command
-allows DCD coordinates to be written "unwrapped" by the image flags
-for each atom.  Unwrapped means that if the atom has passed through
-a periodic boundary one or more times, the value is printed for what
-the coordinate would be if it had not been wrapped back into the
-periodic box.  Note that these coordinates may thus be far outside
-the box size stored with the snapshot.
-
-The {xtc} style writes XTC files, a compressed trajectory format used
-by the GROMACS molecular dynamics package, and described
-"here"_http://manual.gromacs.org/current/online/xtc.html.
-The precision used in XTC files can be adjusted via the
-"dump_modify"_dump_modify.html command.  The default value of 1000
-means that coordinates are stored to 1/1000 nanometer accuracy.  XTC
-files are portable binary files written in the NFS XDR data format,
-so that any machine which supports XDR should be able to read them.
-The number of atoms per snapshot cannot change with the {xtc} style.
-The {unwrap} option of the "dump_modify"_dump_modify.html command allows
-XTC coordinates to be written "unwrapped" by the image flags for each
-atom.  Unwrapped means that if the atom has passed thru a periodic
-boundary one or more times, the value is printed for what the
-coordinate would be if it had not been wrapped back into the periodic
-box.  Note that these coordinates may thus be far outside the box size
-stored with the snapshot.
-
-The {xyz} style writes XYZ files, which is a simple text-based
-coordinate format that many codes can read. Specifically it has
-a line with the number of atoms, then a comment line that is
-usually ignored followed by one line per atom with the atom type
-and the x-, y-, and z-coordinate of that atom. You can use the
-"dump_modify element"_dump_modify.html option to change the output
-from using the (numerical) atom type to an element name (or some
-other label). This will help many visualization programs to guess
-bonds and colors.
-
-Note that {atom}, {custom}, {dcd}, {xtc}, and {xyz} style dump files
-can be read directly by "VMD"_http://www.ks.uiuc.edu/Research/vmd, a
-popular molecular viewing program.
-

-
-Dumps are performed on timesteps that are a multiple of N (including
-timestep 0) and on the last timestep of a minimization if the
-minimization converges.  Note that this means a dump will not be
-performed on the initial timestep after the dump command is invoked,
-if the current timestep is not a multiple of N.  This behavior can be
-changed via the "dump_modify first"_dump_modify.html command, which
-can also be useful if the dump command is invoked after a minimization
-ended on an arbitrary timestep.  N can be changed between runs by
-using the "dump_modify every"_dump_modify.html command (not allowed
-for {dcd} style).  The "dump_modify every"_dump_modify.html command
-also allows a variable to be used to determine the sequence of
-timesteps on which dump files are written.  In this mode a dump on the
-first timestep of a run will also not be written unless the
-"dump_modify first"_dump_modify.html command is used.
-
-The specified filename determines how the dump file(s) is written.
-The default is to write one large text file, which is opened when the
-dump command is invoked and closed when an "undump"_undump.html
-command is used or when LAMMPS exits.  For the {dcd} and {xtc} styles,
-this is a single large binary file.
-
-Dump filenames can contain two wildcard characters.  If a "*"
-character appears in the filename, then one file per snapshot is
-written and the "*" character is replaced with the timestep value.
-For example, tmp.dump.* becomes tmp.dump.0, tmp.dump.10000,
-tmp.dump.20000, etc.  This option is not available for the {dcd} and
-{xtc} styles.  Note that the "dump_modify pad"_dump_modify.html
-command can be used to insure all timestep numbers are the same length
-(e.g. 00010), which can make it easier to read a series of dump files
-in order with some post-processing tools.
-
-If a "%" character appears in the filename, then each of P processors
-writes a portion of the dump file, and the "%" character is replaced
-with the processor ID from 0 to P-1.  For example, tmp.dump.% becomes
-tmp.dump.0, tmp.dump.1, ... tmp.dump.P-1, etc.  This creates smaller
-files and can be a fast mode of output on parallel machines that
-support parallel I/O for output. This option is not available for the
-{dcd}, {xtc}, and {xyz} styles.
-
-By default, P = the number of processors meaning one file per
-processor, but P can be set to a smaller value via the {nfile} or
-{fileper} keywords of the "dump_modify"_dump_modify.html command.
-These options can be the most efficient way of writing out dump files
-when running on large numbers of processors.
-
-Note that using the "*" and "%" characters together can produce a
-large number of small dump files!
-
-For the {atom/mpiio}, {cfg/mpiio}, {custom/mpiio}, and {xyz/mpiio}
-styles, a single dump file is written in parallel via the MPI-IO
-library, which is part of the MPI standard for versions 2.0 and above.
-Using MPI-IO requires two steps.  First, build LAMMPS with its MPIIO
-package installed, e.g.
-
-make yes-mpiio    # installs the MPIIO package
-make mpi          # build LAMMPS for your platform :pre
-
-Second, use a dump filename which contains ".mpiio".  Note that it
-does not have to end in ".mpiio", just contain those characters.
-Unlike MPI-IO restart files, which must be both written and read using
-MPI-IO, the dump files produced by these MPI-IO styles are identical
-in format to the files produced by their non-MPI-IO style
-counterparts.  This means you can write a dump file using MPI-IO and
-use the "read_dump"_read_dump.html command or perform other
-post-processing, just as if the dump file was not written using
-MPI-IO.
-
-Note that MPI-IO dump files are one large file which all processors
-write to.  You thus cannot use the "%" wildcard character described
-above in the filename since that specifies generation of multiple
-files.  You can use the ".bin" suffix described below in an MPI-IO
-dump file; again this file will be written in parallel and have the
-same binary format as if it were written without MPI-IO.
-
-If the filename ends with ".bin", the dump file (or files, if "*" or
-"%" is also used) is written in binary format.  A binary dump file
-will be about the same size as a text version, but will typically
-write out much faster.  Of course, when post-processing, you will need
-to convert it back to text format (see the "binary2txt
-tool"_Section_tools.html#binary) or write your own code to read the
-binary file.  The format of the binary file can be understood by
-looking at the tools/binary2txt.cpp file.  This option is only
-available for the {atom} and {custom} styles.
-
-If the filename ends with ".gz", the dump file (or files, if "*" or "%"
-is also used) is written in gzipped format.  A gzipped dump file will
-be about 3x smaller than the text version, but will also take longer
-to write.  This option is not available for the {dcd} and {xtc}
-styles.
-
-:line
-
-Note that in the discussion which follows, for styles which can
-reference values from a compute or fix, like the {custom}, {cfg}, or
-{local} styles, the bracketed index I can be specified using a
-wildcard asterisk with the index to effectively specify multiple
-values.  This takes the form "*" or "*n" or "n*" or "m*n".  If N = the
-size of the vector (for {mode} = scalar) or the number of columns in
-the array (for {mode} = vector), then an asterisk with no numeric
-values means all indices from 1 to N.  A leading asterisk means all
-indices from 1 to n (inclusive).  A trailing asterisk means all
-indices from n to N (inclusive).  A middle asterisk means all indices
-from m to n (inclusive).
-
-Using a wildcard is the same as if the individual columns of the array
-had been listed one by one.  E.g. these 2 dump commands are
-equivalent, since the "compute stress/atom"_compute_stress_atom.html
-command creates a per-atom array with 6 columns:
-
-compute myPress all stress/atom NULL
-dump 2 all custom 100 tmp.dump id myPress\[*\]
-dump 2 all custom 100 tmp.dump id myPress\[1\] myPress\[2\] myPress\[3\] &
-                                  myPress\[4\] myPress\[5\] myPress\[6\] :pre

-
-This section explains the local attributes that can be specified as
-part of the {local} style.
-
-The {index} attribute can be used to generate an index number from 1
-to N for each line written into the dump file, where N is the total
-number of local datums from all processors, or lines of output that
-will appear in the snapshot.  Note that because data from different
-processors depend on what atoms they currently own, and atoms migrate
-between processor, there is no guarantee that the same index will be
-used for the same info (e.g. a particular bond) in successive
-snapshots.
-
-The {c_ID} and {c_ID\[I\]} attributes allow local vectors or arrays
-calculated by a "compute"_compute.html to be output.  The ID in the
-attribute should be replaced by the actual ID of the compute that has
-been defined previously in the input script.  See the
-"compute"_compute.html command for details.  There are computes for
-calculating local information such as indices, types, and energies for
-bonds and angles.
-
-Note that computes which calculate global or per-atom quantities, as
-opposed to local quantities, cannot be output in a dump local command.
-Instead, global quantities can be output by the "thermo_style
-custom"_thermo_style.html command, and per-atom quantities can be
-output by the dump custom command.
-
-If {c_ID} is used as a attribute, then the local vector calculated by
-the compute is printed.  If {c_ID\[I\]} is used, then I must be in the
-range from 1-M, which will print the Ith column of the local array
-with M columns calculated by the compute.  See the discussion above
-for how I can be specified with a wildcard asterisk to effectively
-specify multiple values.
-
-The {f_ID} and {f_ID\[I\]} attributes allow local vectors or arrays
-calculated by a "fix"_fix.html to be output.  The ID in the attribute
-should be replaced by the actual ID of the fix that has been defined
-previously in the input script.
-
-If {f_ID} is used as a attribute, then the local vector calculated by
-the fix is printed.  If {f_ID\[I\]} is used, then I must be in the
-range from 1-M, which will print the Ith column of the local with M
-columns calculated by the fix.  See the discussion above for how I can
-be specified with a wildcard asterisk to effectively specify multiple
-values.
-
-Here is an example of how to dump bond info for a system, including
-the distance and energy of each bond:
-
-compute 1 all property/local batom1 batom2 btype
-compute 2 all bond/local dist eng
-dump 1 all local 1000 tmp.dump index c_1\[1\] c_1\[2\] c_1\[3\] c_2\[1\] c_2\[2\] :pre

-
-This section explains the atom attributes that can be specified as
-part of the {custom} and {cfg} styles.
-
-The {id}, {mol}, {proc}, {procp1}, {type}, {element}, {mass}, {vx},
-{vy}, {vz}, {fx}, {fy}, {fz}, {q} attributes are self-explanatory.
-
-{Id} is the atom ID.  {Mol} is the molecule ID, included in the data
-file for molecular systems.  {Proc} is the ID of the processor (0 to
-Nprocs-1) that currently owns the atom.  {Procp1} is the proc ID+1,
-which can be convenient in place of a {type} attribute (1 to Ntypes)
-for coloring atoms in a visualization program.  {Type} is the atom
-type (1 to Ntypes).  {Element} is typically the chemical name of an
-element, which you must assign to each type via the "dump_modify
-element"_dump_modify.html command.  More generally, it can be any
-string you wish to associated with an atom type.  {Mass} is the atom
-mass.  {Vx}, {vy}, {vz}, {fx}, {fy}, {fz}, and {q} are components of
-atom velocity and force and atomic charge.
-
-There are several options for outputting atom coordinates.  The {x},
-{y}, {z} attributes write atom coordinates "unscaled", in the
-appropriate distance "units"_units.html (Angstroms, sigma, etc).  Use
-{xs}, {ys}, {zs} if you want the coordinates "scaled" to the box size,
-so that each value is 0.0 to 1.0.  If the simulation box is triclinic
-(tilted), then all atom coords will still be between 0.0 and 1.0.
-I.e. actual unscaled (x,y,z) = xs*A + ys*B + zs*C, where (A,B,C) are
-the non-orthogonal vectors of the simulation box edges, as discussed
-in "Section 6.12"_Section_howto.html#howto_12.
-
-Use {xu}, {yu}, {zu} if you want the coordinates "unwrapped" by the
-image flags for each atom.  Unwrapped means that if the atom has
-passed thru a periodic boundary one or more times, the value is
-printed for what the coordinate would be if it had not been wrapped
-back into the periodic box.  Note that using {xu}, {yu}, {zu} means
-that the coordinate values may be far outside the box bounds printed
-with the snapshot.  Using {xsu}, {ysu}, {zsu} is similar to using
-{xu}, {yu}, {zu}, except that the unwrapped coordinates are scaled by
-the box size. Atoms that have passed through a periodic boundary will
-have the corresponding coordinate increased or decreased by 1.0.
-
-The image flags can be printed directly using the {ix}, {iy}, {iz}
-attributes.  For periodic dimensions, they specify which image of the
-simulation box the atom is considered to be in.  An image of 0 means
-it is inside the box as defined.  A value of 2 means add 2 box lengths
-to get the true value.  A value of -1 means subtract 1 box length to
-get the true value.  LAMMPS updates these flags as atoms cross
-periodic boundaries during the simulation.
-
-The {mux}, {muy}, {muz} attributes are specific to dipolar systems
-defined with an atom style of {dipole}.  They give the orientation of
-the atom's point dipole moment.  The {mu} attribute gives the
-magnitude of the atom's dipole moment.
-
-The {radius} and {diameter} attributes are specific to spherical
-particles that have a finite size, such as those defined with an atom
-style of {sphere}.
-
-The {omegax}, {omegay}, and {omegaz} attributes are specific to
-finite-size spherical particles that have an angular velocity.  Only
-certain atom styles, such as {sphere} define this quantity.
-
-The {angmomx}, {angmomy}, and {angmomz} attributes are specific to
-finite-size aspherical particles that have an angular momentum.  Only
-the {ellipsoid} atom style defines this quantity.
-
-The {tqx}, {tqy}, {tqz} attributes are for finite-size particles that
-can sustain a rotational torque due to interactions with other
-particles.
-
-The {c_ID} and {c_ID\[I\]} attributes allow per-atom vectors or arrays
-calculated by a "compute"_compute.html to be output.  The ID in the
-attribute should be replaced by the actual ID of the compute that has
-been defined previously in the input script.  See the
-"compute"_compute.html command for details.  There are computes for
-calculating the per-atom energy, stress, centro-symmetry parameter,
-and coordination number of individual atoms.
-
-Note that computes which calculate global or local quantities, as
-opposed to per-atom quantities, cannot be output in a dump custom
-command.  Instead, global quantities can be output by the
-"thermo_style custom"_thermo_style.html command, and local quantities
-can be output by the dump local command.
-
-If {c_ID} is used as a attribute, then the per-atom vector calculated
-by the compute is printed.  If {c_ID\[I\]} is used, then I must be in
-the range from 1-M, which will print the Ith column of the per-atom
-array with M columns calculated by the compute.  See the discussion
-above for how I can be specified with a wildcard asterisk to
-effectively specify multiple values.
-
-The {f_ID} and {f_ID\[I\]} attributes allow vector or array per-atom
-quantities calculated by a "fix"_fix.html to be output.  The ID in the
-attribute should be replaced by the actual ID of the fix that has been
-defined previously in the input script.  The "fix
-ave/atom"_fix_ave_atom.html command is one that calculates per-atom
-quantities.  Since it can time-average per-atom quantities produced by
-any "compute"_compute.html, "fix"_fix.html, or atom-style
-"variable"_variable.html, this allows those time-averaged results to
-be written to a dump file.
-
-If {f_ID} is used as a attribute, then the per-atom vector calculated
-by the fix is printed.  If {f_ID\[I\]} is used, then I must be in the
-range from 1-M, which will print the Ith column of the per-atom array
-with M columns calculated by the fix.  See the discussion above for
-how I can be specified with a wildcard asterisk to effectively specify
-multiple values.
-
-The {v_name} attribute allows per-atom vectors calculated by a
-"variable"_variable.html to be output.  The name in the attribute
-should be replaced by the actual name of the variable that has been
-defined previously in the input script.  Only an atom-style variable
-can be referenced, since it is the only style that generates per-atom
-values.  Variables of style {atom} can reference individual atom
-attributes, per-atom atom attributes, thermodynamic keywords, or
-invoke other computes, fixes, or variables when they are evaluated, so
-this is a very general means of creating quantities to output to a
-dump file.
-
-The {d_name} and {i_name} attributes allow to output custom per atom
-floating point or integer properties that are managed by
-"fix property/atom"_fix_property_atom.html.
-
-See "Section 10"_Section_modify.html of the manual for information
-on how to add new compute and fix styles to LAMMPS to calculate
-per-atom quantities which could then be output into dump files.

-[Restrictions:]
-
-To write gzipped dump files, you must either compile LAMMPS with the
--DLAMMPS_GZIP option or use the styles from the COMPRESS package
-- see the "Making LAMMPS"_Section_start.html#start_2 section of
-the documentation.
-
-The {atom/gz}, {cfg/gz}, {custom/gz}, and {xyz/gz} styles are part
-of the COMPRESS package.  They are only enabled if LAMMPS was built
-with that package.  See the "Making
-LAMMPS"_Section_start.html#start_3 section for more info.
-
-The {atom/mpiio}, {cfg/mpiio}, {custom/mpiio}, and {xyz/mpiio} styles
-are part of the MPIIO package.  They are only enabled if LAMMPS was
-built with that package.  See the "Making
-LAMMPS"_Section_start.html#start_3 section for more info.
-
-The {xtc} style is part of the MISC package.  It is only enabled if
-LAMMPS was built with that package.  See the "Making
-LAMMPS"_Section_start.html#start_3 section for more info.

-[Description:]
-
-Modify the parameters of a previously defined dump command.  Not all
-parameters are relevant to all dump styles.
-
-As explained on the "dump"_dump.html doc page, the {atom/mpiio},
-{custom/mpiio}, and {xyz/mpiio} dump styles are identical in command
-syntax and in the format of the dump files they create, to the
-corresponding styles without "mpiio", except the single dump file they
-produce is written in parallel via the MPI-IO library.  Thus if a
-dump_modify option below is valid for the {atom} style, it is also
-valid for the {atom/mpiio} style, and similarly for the other styles
-which allow for use of MPI-IO.

-
-These keywords apply to various dump styles, including the "dump

-
-The {append} keyword applies to all dump styles except {cfg} and {xtc}
-and {dcd}.  It also applies only to text output files, not to binary
-or gzipped or image/movie files.  If specified as {yes}, then dump
-snapshots are appended to the end of an existing dump file.  If
-specified as {no}, then a new dump file will be created which will
-overwrite an existing file with the same name.
-
-:line
-
-The {at} keyword only applies to the {netcdf} dump style.  It can only
-be used if the {append yes} keyword is also used.  The {N} argument is
-the index of which frame to append to.  A negative value can be
-specified for {N}, which means a frame counted from the end of the
-file.  The {at} keyword can only be used if the dump_modify command is
-before the first command that causes dump snapshots to be output,
-e.g. a "run"_run.html or "minimize"_minimize.html command.  Once the
-dump file has been opened, this keyword has no further effect.
-
-:line
-
-The {buffer} keyword applies only to dump styles {atom}, {cfg},
-{custom}, {local}, and {xyz}.  It also applies only to text output
-files, not to binary or gzipped files.  If specified as {yes}, which
-is the default, then each processor writes its output into an internal
-text buffer, which is then sent to the processor(s) which perform file
-writes, and written by those processors(s) as one large chunk of text.
-If specified as {no}, each processor sends its per-atom data in binary
-format to the processor(s) which perform file wirtes, and those
-processor(s) format and write it line by line into the output file.
-
-The buffering mode is typically faster since each processor does the
-relatively expensive task of formatting the output for its own atoms.
-However it requires about twice the memory (per processor) for the
-extra buffering.
-
-:line
-
-The {delay} keyword applies to all dump styles.  No snapshots will be
-output until the specified {Dstep} timestep or later.  Specifying
-{Dstep} < 0 is the same as turning off the delay setting.  This is a
-way to turn off unwanted output early in a simulation, for example,
-during an equilibration phase.
-
-:line
-
-The {element} keyword applies only to the dump {cfg}, {xyz}, and
-{image} styles.  It associates element names (e.g. H, C, Fe) with
-LAMMPS atom types.  See the list of element names at the bottom of
-this page.
-
-In the case of dump {cfg}, this allows the "AtomEye"_atomeye
-visualization package to read the dump file and render atoms with the
-appropriate size and color.
-
-In the case of dump {image}, the output images will follow the same
-"AtomEye"_atomeye convention.  An element name is specified for each
-atom type (1 to Ntype) in the simulation.  The same element name can
-be given to multiple atom types.
-
-In the case of {xyz} format dumps, there are no restrictions to what
-label can be used as an element name.  Any whitespace separated text
-will be accepted.

-
-The {every} keyword changes the dump frequency originally specified by
-the "dump"_dump.html command to a new value.  The every keyword can be
-specified in one of two ways.  It can be a numeric value in which case
-it must be > 0.  Or it can be an "equal-style variable"_variable.html,
-which should be specified as v_name, where name is the variable name.
-
-In this case, the variable is evaluated at the beginning of a run to
-determine the next timestep at which a dump snapshot will be written
-out.  On that timestep the variable will be evaluated again to
-determine the next timestep, etc.  Thus the variable should return
-timestep values.  See the stagger() and logfreq() and stride() math
-functions for "equal-style variables"_variable.html, as examples of
-useful functions to use in this context.  Other similar math functions
-could easily be added as options for "equal-style
-variables"_variable.html.  Also see the next() function, which allows
-use of a file-style variable which reads successive values from a
-file, each time the variable is evaluated.  Used with the {every}
-keyword, if the file contains a list of ascending timesteps, you can
-output snapshots whenever you wish.
-
-Note that when using the variable option with the {every} keyword, you
-need to use the {first} option if you want an initial snapshot written
-to the dump file.  The {every} keyword cannot be used with the dump
-{dcd} style.
-
-For example, the following commands will
-write snapshots at timesteps 0,10,20,30,100,200,300,1000,2000,etc:
-
-variable        s equal logfreq(10,3,10)
-dump            1 all atom 100 tmp.dump
-dump_modify     1 every v_s first yes :pre
-
-The following commands would write snapshots at the timesteps listed
-in file tmp.times:
-
-variable        f file tmp.times
-variable        s equal next(f)
-dump            1 all atom 100 tmp.dump
-dump_modify     1 every v_s :pre
-
-NOTE: When using a file-style variable with the {every} keyword, the
-file of timesteps must list a first timestep that is beyond the
-current timestep (e.g. it cannot be 0).  And it must list one or more
-timesteps beyond the length of the run you perform.  This is because
-the dump command will generate an error if the next timestep it reads
-from the file is not a value greater than the current timestep.  Thus
-if you wanted output on steps 0,15,100 of a 100-timestep run, the file
-should contain the values 15,100,101 and you should also use the
-dump_modify first command.  Any final value > 100 could be used in
-place of 101.
-
-:line
-
-The {first} keyword determines whether a dump snapshot is written on
-the very first timestep after the dump command is invoked.  This will
-always occur if the current timestep is a multiple of N, the frequency
-specified in the "dump"_dump.html command, including timestep 0.  But
-if this is not the case, a dump snapshot will only be written if the
-setting of this keyword is {yes}.  If it is {no}, which is the
-default, then it will not be written.
-
-:line
-
-The {flush} keyword determines whether a flush operation is invoked
-after a dump snapshot is written to the dump file.  A flush insures
-the output in that file is current (no buffering by the OS), even if
-LAMMPS halts before the simulation completes.  Flushes cannot be
-performed with dump style {xtc}.
-
-:line
-
-The {format} keyword can be used to change the default numeric format
-output by the text-based dump styles: {atom}, {custom}, {cfg}, and
-{xyz} styles, and their MPIIO variants.  Only the {line} or {none}
-options can be used with the {atom} and {xyz} styles.
-
-All the specified format strings are C-style formats, e.g. as used by
-the C/C++ printf() command.  The {line} keyword takes a single
-argument which is the format string for an entire line of output for
-each atom (do not include a trailing "\n"), with N fields, which you
-must enclose in quotes if it is more than one field.  The {int} and
-{float} keywords take a single format argument and are applied to all
-integer or floating-point quantities output.  The setting for {M
-string} also takes a single format argument which is used for the Mth
-value output in each line, e.g. the 5th column is output in high
-precision for "format 5 %20.15g".
-
-NOTE: When using the {line} keyword for the {cfg} style, the first two
-fields (atom ID and type) are not actually written into the CFG file,
-however you must include formats for them in the format string.
-
-The {format} keyword can be used multiple times.  The precedence is
-that for each value in a line of output, the {M} format (if specified)
-is used, else the {int} or {float} setting (if specified) is used,
-else the {line} setting (if specified) for that value is used, else
-the default setting is used.  A setting of {none} clears all previous
-settings, reverting all values to their default format.
-
-NOTE: Atom and molecule IDs are stored internally as 4-byte or 8-byte
-signed integers, depending on how LAMMPS was compiled.  When
-specifying the {format int} option you can use a "%d"-style format
-identifier in the format string and LAMMPS will convert this to the
-corresponding 8-byte form it it is needed when outputting those
-values.  However, when specifying the {line} option or {format M
-string} option for those values, you should specify a format string
-appropriate for an 8-byte signed integer, e.g. one with "%ld", if
-LAMMPS was compiled with the -DLAMMPS_BIGBIG option for 8-byte IDs.
-
-NOTE: Any value written to a text-based dump file that is a per-atom
-quantity calculated by a "compute"_compute.html or "fix"_fix.html is
-stored internally as a floating-point value.  If the value is actually
-an integer and you wish it to appear in the text dump file as a
-(large) integer, then you need to use an appropriate format.  For
-example, these commands:
-
-compute     1 all property/local batom1 batom2
-dump        1 all local 100 tmp.bonds index c_1\[1\] c_1\[2\]
-dump_modify 1 format "%d %0.0f %0.0f" :pre
-
-will output the two atom IDs for atoms in each bond as integers.  If
-the dump_modify command were omitted, they would appear as
-floating-point values, assuming they were large integers (more than 6
-digits).  The "index" keyword should use the "%d" format since it is
-not generated by a compute or fix, and is stored internally as an
-integer.
-
-:line
-
-The {fileper} keyword is documented below with the {nfile} keyword.
-
-:line
-
-The {image} keyword applies only to the dump {atom} style.  If the
-image value is {yes}, 3 flags are appended to each atom's coords which
-are the absolute box image of the atom in each dimension.  For
-example, an x image flag of -2 with a normalized coord of 0.5 means
-the atom is in the center of the box, but has passed thru the box
-boundary 2 times and is really 2 box lengths to the left of its
-current coordinate.  Note that for dump style {custom} these various
-values can be printed in the dump file by using the appropriate atom
-attributes in the dump command itself.
-
-:line
-
-The {label} keyword applies only to the dump {local} style.  When
-it writes local information, such as bond or angle topology
-to a dump file, it will use the specified {label} to format
-the header.  By default this includes 2 lines:
-
-ITEM: NUMBER OF ENTRIES
-ITEM: ENTRIES ... :pre
-
-The word "ENTRIES" will be replaced with the string specified,
-e.g. BONDS or ANGLES.
-
-:line
-
-The {nfile} or {fileper} keywords can be used in conjunction with the
-"%" wildcard character in the specified dump file name, for all dump
-styles except the {dcd}, {image}, {movie}, {xtc}, and {xyz} styles
-(for which "%" is not allowed).  As explained on the "dump"_dump.html
-command doc page, the "%" character causes the dump file to be written
-in pieces, one piece for each of P processors.  By default P = the
-number of processors the simulation is running on.  The {nfile} or
-{fileper} keyword can be used to set P to a smaller value, which can
-be more efficient when running on a large number of processors.
-
-The {nfile} keyword sets P to the specified Nf value.  For example, if
-Nf = 4, and the simulation is running on 100 processors, 4 files will
-be written, by processors 0,25,50,75.  Each will collect information
-from itself and the next 24 processors and write it to a dump file.
-
-For the {fileper} keyword, the specified value of Np means write one
-file for every Np processors.  For example, if Np = 4, every 4th
-processor (0,4,8,12,etc) will collect information from itself and the
-next 3 processors and write it to a dump file.
-
-:line
-
-The {pad} keyword only applies when the dump filename is specified
-with a wildcard "*" character which becomes the timestep.  If {pad} is
-0, which is the default, the timestep is converted into a string of
-unpadded length, e.g. 100 or 12000 or 2000000.  When {pad} is
-specified with {Nchar} > 0, the string is padded with leading zeroes
-so they are all the same length = {Nchar}.  For example, pad 7 would
-yield 0000100, 0012000, 2000000.  This can be useful so that
-post-processing programs can easily read the files in ascending
-timestep order.
-
-:line
-
-The {pbc} keyword applies to all the dump styles.  As explained on the
-"dump"_dump.html doc page, atom coordinates in a dump file may be
-slightly outside the simulation box.  This is because periodic
-boundary conditions are enforced only on timesteps when neighbor lists
-are rebuilt, which will not typically coincide with the timesteps dump
-snapshots are written.  If the setting of this keyword is set to
-{yes}, then all atoms will be remapped to the periodic box before the
-snapshot is written, then restored to their original position.  If it
-is set to {no} they will not be.  The {no} setting is the default
-because it requires no extra computation.
-
-:line
-
-The {precision} keyword only applies to the dump {xtc} style.  A
-specified value of N means that coordinates are stored to 1/N
-nanometer accuracy, e.g. for N = 1000, the coordinates are written to
-1/1000 nanometer accuracy.
-
-:line
-
-The {refresh} keyword only applies to the dump {custom}, {cfg},
-{image}, and {movie} styles.  It allows an "incremental" dump file to
-be written, by refreshing a compute that is used as a threshold for
-determining which atoms are included in a dump snapshot.  The
-specified {c_ID} gives the ID of the compute.  It is prefixed by "c_"
-to indicate a compute, which is the only current option.  At some
-point, other options may be added, e.g. fixes or variables.
-
-NOTE: This keyword can only be specified once for a dump.  Refreshes
-of multiple computes cannot yet be performed.
-
-The definition and motivation of an incremental dump file is as
-follows.  Instead of outputting all atoms at each snapshot (with some
-associated values), you may only wish to output the subset of atoms
-with a value that has changed in some way compared to the value the
-last time that atom was output.  In some scenarios this can result in
-a dramatically smaller dump file.  If desired, by post-processing the
-sequence of snapshots, the values for all atoms at all timesteps can
-be inferred.
-
-A concrete example is a simulation of atom diffusion in a solid,
-represented as atoms on a lattice.  Diffusive hops are rare.  Imagine
-that when a hop occurs an atom moves more than a distance {Dhop}.  For
-any snapshot we only want to output atoms that have hopped since the
-last snapshot.  This can be accomplished with something the following
-commands:
-
-variable        Dhop equal 0.6
-variable        check atom "c_dsp[4] > v_Dhop"
-compute         dsp all displace/atom refresh check
-dump            1 all custom 20 tmp.dump id type x y z
-dump_modify     1 append yes thresh c_dsp[4] > ${Dhop} refresh c_dsp :pre
-
-The "compute displace/atom"_compute_displace_atom.html command
-calculates the displacement of each atom from its reference position.
-The "4" index is the scalar displacement; 1,2,3 are the xyz components
-of the displacement.  The "dump_modify thresh"_dump_modify.html
-command will cause only atoms that have displaced more than 0.6
-Angstroms to be output on a given snapshot (assuming metal units).
-However, note that when an atom is output, we also need to update the
-reference position for that atom to its new coordinates.  So that it
-will not be output in every snapshot thereafter.  That reference
-position is stored by "compute
-displace/atom"_compute_displace_atom.html.  So the dump_modify
-{refresh} option triggers a call to compute displace/atom at the end
-of every dump to perform that update.  The {refresh check} option
-shown as part of the "compute
-displace/atom"_compute_displace_atom.html command enables the compute
-to respond to the call from the dump command, and update the
-appropriate reference positions.  This is done be defining an
-"atom-style variable"_variable.html, {check} in this example, which
-calculates a Boolean value (0 or 1) for each atom, based on the same
-criterion used by dump_modify thresh.  
-
-See the "compute displace/atom"_compute_displace_atom.html command for
-more details, including an example of how to produce output that
-includes an initial snapshot with the reference position of all atoms.
-
-Note that only computes with a {refresh} option will work with
-dump_modify refresh.  See individual compute doc pages for details.
-Currently, only compute displace/atom supports this option.  Others
-may be added at some point.  If you use a compute that doesn't support
-refresh operations, LAMMPS will not complain; dump_modify refresh will
-simply do nothing.
-
-:line
-
-The {region} keyword only applies to the dump {custom}, {cfg},
-{image}, and {movie} styles.  If specified, only atoms in the region
-will be written to the dump file or included in the image/movie.  Only
-one region can be applied as a filter (the last one specified).  See
-the "region"_region.html command for more details.  Note that a region
-can be defined as the "inside" or "outside" of a geometric shape, and
-it can be the "union" or "intersection" of a series of simpler
-regions.
-
-:line
-
-The {scale} keyword applies only to the dump {atom} style.  A scale
-value of {yes} means atom coords are written in normalized units from
-0.0 to 1.0 in each box dimension.  If the simulation box is triclinic
-(tilted), then all atom coords will still be between 0.0 and 1.0.  A
-value of {no} means they are written in absolute distance units
-(e.g. Angstroms or sigma).
-
-:line
-
-The {sfactor} and {tfactor} keywords only apply to the dump {xtc}
-style.  They allow customization of the unit conversion factors used
-when writing to XTC files.  By default they are initialized for
-whatever "units"_units.html style is being used, to write out
-coordinates in nanometers and time in picoseconds.  I.e. for {real}
-units, LAMMPS defines {sfactor} = 0.1 and {tfactor} = 0.001, since the
-Angstroms and fmsec used by {real} units are 0.1 nm and 0.001 psec
-respectively.  If you are using a units system with distance and time
-units far from nm and psec, you may wish to write XTC files with
-different units, since the compression algorithm used in XTC files is
-most effective when the typical magnitude of position data is between
-10.0 and 0.1.
-
-:line
-
-The {sort} keyword determines whether lines of per-atom output in a
-snapshot are sorted or not.  A sort value of {off} means they will
-typically be written in indeterminate order, either in serial or
-parallel.  This is the case even in serial if the "atom_modify
-sort"_atom_modify.html option is turned on, which it is by default, to
-improve performance.  A sort value of {id} means sort the output by
-atom ID.  A sort value of N or -N means sort the output by the value
-in the Nth column of per-atom info in either ascending or descending
-order.
-
-The dump {local} style cannot be sorted by atom ID, since there are
-typically multiple lines of output per atom.  Some dump styles, such
-as {dcd} and {xtc}, require sorting by atom ID to format the output
-file correctly.  If multiple processors are writing the dump file, via
-the "%" wildcard in the dump filename, then sorting cannot be
-performed.
-
-NOTE: Unless it is required by the dump style, sorting dump file
-output requires extra overhead in terms of CPU and communication cost,
-as well as memory, versus unsorted output.
-
-:line
-
-The {thermo} keyword only applies the dump {netcdf} style.  It
-triggers writing of "thermo"_thermo.html information to the dump file
-alongside per-atom data.  The values included in the dump file are
-identical to the values specified by "thermo_style"_thermo_style.html.
-
-:line
-
-The {thresh} keyword only applies to the dump {custom}, {cfg},
-{image}, and {movie} styles.  Multiple thresholds can be specified.
-Specifying {none} turns off all threshold criteria.  If thresholds are
-specified, only atoms whose attributes meet all the threshold criteria
-are written to the dump file or included in the image.  The possible
-attributes that can be tested for are the same as those that can be
-specified in the "dump custom"_dump.html command, with the exception
-of the {element} attribute, since it is not a numeric value.  Note
-that a different attributes can be used than those output by the "dump
-custom"_dump.html command.  E.g. you can output the coordinates and
-stress of atoms whose energy is above some threshold.
-
-If an atom-style variable is used as the attribute, then it can
-produce continuous numeric values or effective Boolean 0/1 values
-which may be useful for the comparison operator.  Boolean values can
-be generated by variable formulas that use comparison or Boolean math
-operators or special functions like gmask() and rmask() and grmask().
-See the "variable"_variable.html command doc page for details.
-
-The specified value must be a simple numeric value or the word LAST.
-If LAST is used, it refers to the value of the attribute the last time
-the dump command was invoked to produce a snapshot.  This is a way to
-only dump atoms whose attribute has changed (or not changed).
-Three examples follow.
-
-dump_modify ... thresh ix != LAST :pre
-
-This will dump atoms which have crossed the periodic x boundary of the
-simulation box since the last dump.  (Note that atoms that crossed
-once and then crossed back between the two dump timesteps would not be
-included.)
-
-region foo sphere 10 20 10 15
-variable inregion atom rmask(foo)
-dump_modify ... thresh v_inregion |^ LAST
-
-This will dump atoms which crossed the boundary of the spherical
-region since the last dump.
-
-variable charge atom "(q > 0.5) || (q < -0.5)"
-dump_modify ... thresh v_charge |^ LAST
-
-This will dump atoms whose charge has changed from an absolute value
-less than 1/2 to greater than 1/2 (or vice versa) since the last dump.
-E.g. due to reactions and subsequent charge equilibration in a
-reactive force field.
-
-The choice of operators listed above are the usual comparison
-operators.  The XOR operation (exclusive or) is also included as "|^".
-In this context, XOR means that if either the attribute or value is
-0.0 and the other is non-zero, then the result is "true" and the
-threshold criterion is met.  Otherwise it is not met.
-
-:line
-
-The {unwrap} keyword only applies to the dump {dcd} and {xtc} styles.
-If set to {yes}, coordinates will be written "unwrapped" by the image
-flags for each atom.  Unwrapped means that if the atom has passed thru
-a periodic boundary one or more times, the value is printed for what
-the coordinate would be if it had not been wrapped back into the
-periodic box.  Note that these coordinates may thus be far outside the
-box size stored with the snapshot.
-
-:line
-:line
-
-These keywords apply only to the "dump image"_dump_image.html and
-"dump movie"_dump_image.html styles.  Any keyword that affects an
-image, also affects a movie, since the movie is simply a collection of
-images.  Some of the keywords only affect the "dump
-movie"_dump_image.html style.  The descriptions give details.
-
-:line
-
-The {acolor} keyword can be used with the "dump image"_dump_image.html
-command, when its atom color setting is {type}, to set the color that
-atoms of each type will be drawn in the image.
-
-The specified {type} should be an integer from 1 to Ntypes = the
-number of atom types.  A wildcard asterisk can be used in place of or
-in conjunction with the {type} argument to specify a range of atom
-types.  This takes the form "*" or "*n" or "n*" or "m*n".  If N = the
-number of atom types, then an asterisk with no numeric values means
-all types from 1 to N.  A leading asterisk means all types from 1 to n
-(inclusive).  A trailing asterisk means all types from n to N
-(inclusive).  A middle asterisk means all types from m to n
-(inclusive).
-
-The specified {color} can be a single color which is any of the 140
-pre-defined colors (see below) or a color name defined by the
-dump_modify color option.  Or it can be two or more colors separated
-by a "/" character, e.g. red/green/blue.  In the former case, that
-color is assigned to all the specified atom types.  In the latter
-case, the list of colors are assigned in a round-robin fashion to each
-of the specified atom types.
-
-:line
-
-The {adiam} keyword can be used with the "dump image"_dump_image.html
-command, when its atom diameter setting is {type}, to set the size
-that atoms of each type will be drawn in the image.  The specified
-{type} should be an integer from 1 to Ntypes.  As with the {acolor}
-keyword, a wildcard asterisk can be used as part of the {type}
-argument to specify a range of atomt types.  The specified {diam} is
-the size in whatever distance "units"_units.html the input script is
-using, e.g. Angstroms.
-
-:line
-
-The {amap} keyword can be used with the "dump image"_dump_image.html
-command, with its {atom} keyword, when its atom setting is an
-atom-attribute, to setup a color map.  The color map is used to assign
-a specific RGB (red/green/blue) color value to an individual atom when
-it is drawn, based on the atom's attribute, which is a numeric value,
-e.g. its x-component of velocity if the atom-attribute "vx" was
-specified.
-
-The basic idea of a color map is that the atom-attribute will be
-within a range of values, and that range is associated with a series
-of colors (e.g. red, blue, green).  An atom's specific value (vx =
--3.2) can then mapped to the series of colors (e.g. halfway between
-red and blue), and a specific color is determined via an interpolation
-procedure.
-
-There are many possible options for the color map, enabled by the
-{amap} keyword.  Here are the details.
-
-The {lo} and {hi} settings determine the range of values allowed for
-the atom attribute.  If numeric values are used for {lo} and/or {hi},
-then values that are lower/higher than that value are set to the
-value.  I.e. the range is static.  If {lo} is specified as {min} or
-{hi} as {max} then the range is dynamic, and the lower and/or
-upper bound will be calculated each time an image is drawn, based
-on the set of atoms being visualized.
-
-The {style} setting is two letters, such as "ca".  The first letter is
-either "c" for continuous, "d" for discrete, or "s" for sequential.
-The second letter is either "a" for absolute, or "f" for fractional.
-
-A continuous color map is one in which the color changes continuously
-from value to value within the range.  A discrete color map is one in
-which discrete colors are assigned to sub-ranges of values within the
-range.  A sequential color map is one in which discrete colors are
-assigned to a sequence of sub-ranges of values covering the entire
-range.
-
-An absolute color map is one in which the values to which colors are
-assigned are specified explicitly as values within the range.  A
-fractional color map is one in which the values to which colors are
-assigned are specified as a fractional portion of the range.  For
-example if the range is from -10.0 to 10.0, and the color red is to be
-assigned to atoms with a value of 5.0, then for an absolute color map
-the number 5.0 would be used.  But for a fractional map, the number
-0.75 would be used since 5.0 is 3/4 of the way from -10.0 to 10.0.
-
-The {delta} setting must be specified for all styles, but is only used
-for the sequential style; otherwise the value is ignored.  It
-specifies the bin size to use within the range for assigning
-consecutive colors to.  For example, if the range is from -10.0 to
-10.0 and a {delta} of 1.0 is used, then 20 colors will be assigned to
-the range.  The first will be from -10.0 <= color1 < -9.0, then 2nd
-from -9.0 <= color2 < -8.0, etc.
-
-The {N} setting is how many entries follow.  The format of the entries
-depends on whether the color map style is continuous, discrete or
-sequential.  In all cases the {color} setting can be any of the 140
-pre-defined colors (see below) or a color name defined by the
-dump_modify color option.
-
-For continuous color maps, each entry has a {value} and a {color}.
-The {value} is either a number within the range of values or {min} or
-{max}.  The {value} of the first entry must be {min} and the {value}
-of the last entry must be {max}.  Any entries in between must have
-increasing values.  Note that numeric values can be specified either
-as absolute numbers or as fractions (0.0 to 1.0) of the range,
-depending on the "a" or "f" in the style setting for the color map.
-
-Here is how the entries are used to determine the color of an
-individual atom, given the value X of its atom attribute.  X will fall
-between 2 of the entry values.  The color of the atom is linearly
-interpolated (in each of the RGB values) between the 2 colors
-associated with those entries.  For example, if X = -5.0 and the 2
-surrounding entries are "red" at -10.0 and "blue" at 0.0, then the
-atom's color will be halfway between "red" and "blue", which happens
-to be "purple".
-
-For discrete color maps, each entry has a {lo} and {hi} value and a
-{color}.  The {lo} and {hi} settings are either numbers within the
-range of values or {lo} can be {min} or {hi} can be {max}.  The {lo}
-and {hi} settings of the last entry must be {min} and {max}.  Other
-entries can have any {lo} and {hi} values and the sub-ranges of
-different values can overlap.  Note that numeric {lo} and {hi} values
-can be specified either as absolute numbers or as fractions (0.0 to
-1.0) of the range, depending on the "a" or "f" in the style setting
-for the color map.
-
-Here is how the entries are used to determine the color of an
-individual atom, given the value X of its atom attribute.  The entries
-are scanned from first to last.  The first time that {lo} <= X <=
-{hi}, X is assigned the color associated with that entry.  You can
-think of the last entry as assigning a default color (since it will
-always be matched by X), and the earlier entries as colors that
-override the default.  Also note that no interpolation of a color RGB
-is done.  All atoms will be drawn with one of the colors in the list
-of entries.
-
-For sequential color maps, each entry has only a {color}.  Here is how
-the entries are used to determine the color of an individual atom,
-given the value X of its atom attribute.  The range is partitioned
-into N bins of width {binsize}.  Thus X will fall in a specific bin
-from 1 to N, say the Mth bin.  If it falls on a boundary between 2
-bins, it is considered to be in the higher of the 2 bins.  Each bin is
-assigned a color from the E entries.  If E < N, then the colors are
-repeated.  For example if 2 entries with colors red and green are
-specified, then the odd numbered bins will be red and the even bins
-green.  The color of the atom is the color of its bin.  Note that the
-sequential color map is really a shorthand way of defining a discrete
-color map without having to specify where all the bin boundaries are.
-
-Here is an example of using a sequential color map to color all the
-atoms in individual molecules with a different color.  See the
-examples/pour/in.pour.2d.molecule input script for an example of how
-this is used.
-
-variable        colors string &
-                "red green blue yellow white &

-                zoom 1.6 adiam 1.5
-dump_modify     1 pad 5 amap 0 10 sa 1 10 $\{colors\} :pre
-
-In this case, 10 colors are defined, and molecule IDs are
-mapped to one of the colors, even if there are 1000s of molecules.
-
-:line
-
-The {backcolor} sets the background color of the images.  The color
-name can be any of the 140 pre-defined colors (see below) or a color
-name defined by the dump_modify color option.
-
-:line
-
-The {bcolor} keyword can be used with the "dump image"_dump_image.html
-command, with its {bond} keyword, when its color setting is {type}, to
-set the color that bonds of each type will be drawn in the image.
-
-The specified {type} should be an integer from 1 to Nbondtypes = the
-number of bond types.  A wildcard asterisk can be used in place of or
-in conjunction with the {type} argument to specify a range of bond
-types.  This takes the form "*" or "*n" or "n*" or "m*n".  If N = the
-number of bond types, then an asterisk with no numeric values means
-all types from 1 to N.  A leading asterisk means all types from 1 to n
-(inclusive).  A trailing asterisk means all types from n to N
-(inclusive).  A middle asterisk means all types from m to n
-(inclusive).
-
-The specified {color} can be a single color which is any of the 140
-pre-defined colors (see below) or a color name defined by the
-dump_modify color option.  Or it can be two or more colors separated
-by a "/" character, e.g. red/green/blue.  In the former case, that
-color is assigned to all the specified bond types.  In the latter
-case, the list of colors are assigned in a round-robin fashion to each
-of the specified bond types.
-
-:line
-
-The {bdiam} keyword can be used with the "dump image"_dump_image.html
-command, with its {bond} keyword, when its diam setting is {type}, to
-set the diameter that bonds of each type will be drawn in the image.
-The specified {type} should be an integer from 1 to Nbondtypes.  As
-with the {bcolor} keyword, a wildcard asterisk can be used as part of
-the {type} argument to specify a range of bond types.  The specified
-{diam} is the size in whatever distance "units"_units.html you are
-using, e.g. Angstroms.
-
-:line
-
-The {bitrate} keyword can be used with the "dump
-movie"_dump_image.html command to define the size of the resulting
-movie file and its quality via setting how many kbits per second are
-to be used for the movie file. Higher bitrates require less
-compression and will result in higher quality movies.  The quality is
-also determined by the compression format and encoder.  The default
-setting is 2000 kbit/s, which will result in average quality with
-older compression formats.
-
-NOTE: Not all movie file formats supported by dump movie allow the
-bitrate to be set.  If not, the setting is silently ignored.
-
-:line
-
-The {boxcolor} keyword sets the color of the simulation box drawn
-around the atoms in each image as well as the color of processor
-sub-domain boundaries.  See the "dump image box" command for how to
-specify that a box be drawn via the {box} keyword, and the sub-domain
-boundaries via the {subbox} keyword.  The color name can be any of the
-140 pre-defined colors (see below) or a color name defined by the
-dump_modify color option.
-
-:line
-
-The {color} keyword allows definition of a new color name, in addition
-to the 140-predefined colors (see below), and associates 3
-red/green/blue RGB values with that color name.  The color name can
-then be used with any other dump_modify keyword that takes a color
-name as a value.  The RGB values should each be floating point values
-between 0.0 and 1.0 inclusive.
-
-When a color name is converted to RGB values, the user-defined color
-names are searched first, then the 140 pre-defined color names.  This
-means you can also use the {color} keyword to overwrite one of the
-pre-defined color names with new RBG values.
-
-:line
-
-The {framerate} keyword can be used with the "dump
-movie"_dump_image.html command to define the duration of the resulting
-movie file.  Movie files written by the dump {movie} command have a
-default frame rate of 24 frames per second and the images generated
-will be converted at that rate.  Thus a sequence of 1000 dump images
-will result in a movie of about 42 seconds.  To make a movie run
-longer you can either generate images more frequently or lower the
-frame rate.  To speed a movie up, you can do the inverse.  Using a
-frame rate higher than 24 is not recommended, as it will result in
-simply dropping the rendered images. It is more efficient to dump
-images less frequently.

+
+The {refresh} option can be used in conjuction with the "dump_modify
+refresh" command to generate incremental dump files.
+
+The definition and motivation of an incremental dump file is as
+follows.  Instead of outputting all atoms at each snapshot (with some
+associated values), you may only wish to output the subset of atoms
+with a value that has changed in some way compared to the value the
+last time that atom was output.  In some scenarios this can result in
+a dramatically smaller dump file.  If desired, by post-processing the
+sequence of snapshots, the values for all atoms at all timesteps can
+be inferred.
+
+A concrete example using this compute, is a simulation of atom
+diffusion in a solid, represented as atoms on a lattice.  Diffusive
+hops are rare.  Imagine that when a hop occurs an atom moves more than
+a distance {Dhop}.  For any snapshot we only want to output atoms that
+have hopped since the last snapshot.  This can be accomplished with
+something like the following commands:
+
+write_dump      all custom tmp.dump id type x y z    # see comment below :pre
+
+variable        Dhop equal 0.6
+variable        check atom "c_dsp[4] > v_Dhop"
+compute         dsp all displace/atom refresh check
+dump            1 all custom 100 tmp.dump id type x y z
+dump_modify     1 append yes thresh c_dsp[4] > ${Dhop} &
+                refresh c_dsp delay 100 :pre
+
+The "dump_modify thresh"_dump_modify.html command will only ouptut
+atoms that have displaced more than 0.6 Angstroms on each snapshot
+(assuming metal units).  The dump_modify {refresh} option triggers a
+call to this compute at the end of every dump.
+
+The {refresh} argument for this compute is the ID of an "atom-style
+variable"_variable.html which calculates a Boolean value (0 or 1)
+based on the same criterion used by dump_modify thresh.  This compute
+evaluates the atom-style variable.  For each atom that returns 1
+(true), the original (reference) coordinates of the atom (stored by
+this compute) are updated.
+
+The effect of these commands is that a particular atom will only be
+output in the dump file on the snapshot after it makes a diffusive
+hop.  It will not be output again until it makes another hop.
+
+Note that in the first snapshot of a subsequent run, no atoms will be
+typically be output.  That is because the initial displacement for all
+atoms is 0.0.  If an initial dump snapshot is desired, containing the
+initial reference positions of all atoms, one way to do this is
+illustrated above.  An initial write_dump command can be used before
+the first run.  It will contain the positions of all the atoms,

+The {refresh} keyword only applies to the dump {custom}, {cfg},
+{image}, and {movie} styles.  It allows an "incremental" dump file to
+be written, by refreshing a compute that is used as a threshold for
+determining which atoms are included in a dump snapshot.  The
+specified {c_ID} gives the ID of the compute.  It is prefixed by "c_"
+to indicate a compute, which is the only current option.  At some
+point, other options may be added, e.g. fixes or variables.
+
+NOTE: This keyword can only be specified once for a dump.  Refreshes
+of multiple computes cannot yet be performed.
+
+The definition and motivation of an incremental dump file is as
+follows.  Instead of outputting all atoms at each snapshot (with some
+associated values), you may only wish to output the subset of atoms
+with a value that has changed in some way compared to the value the
+last time that atom was output.  In some scenarios this can result in
+a dramatically smaller dump file.  If desired, by post-processing the
+sequence of snapshots, the values for all atoms at all timesteps can
+be inferred.
+
+A concrete example is a simulation of atom diffusion in a solid,
+represented as atoms on a lattice.  Diffusive hops are rare.  Imagine
+that when a hop occurs an atom moves more than a distance {Dhop}.  For
+any snapshot we only want to output atoms that have hopped since the
+last snapshot.  This can be accomplished with something the following
+commands:
+
+variable        Dhop equal 0.6
+variable        check atom "c_dsp[4] > v_Dhop"
+compute         dsp all displace/atom refresh check
+dump            1 all custom 20 tmp.dump id type x y z
+dump_modify     1 append yes thresh c_dsp[4] > ${Dhop} refresh c_dsp :pre
+
+The "compute displace/atom"_compute_displace_atom.html command
+calculates the displacement of each atom from its reference position.
+The "4" index is the scalar displacement; 1,2,3 are the xyz components
+of the displacement.  The "dump_modify thresh"_dump_modify.html
+command will cause only atoms that have displaced more than 0.6
+Angstroms to be output on a given snapshot (assuming metal units).
+However, note that when an atom is output, we also need to update the
+reference position for that atom to its new coordinates.  So that it
+will not be output in every snapshot thereafter.  That reference
+position is stored by "compute
+displace/atom"_compute_displace_atom.html.  So the dump_modify
+{refresh} option triggers a call to compute displace/atom at the end
+of every dump to perform that update.  The {refresh check} option
+shown as part of the "compute
+displace/atom"_compute_displace_atom.html command enables the compute
+to respond to the call from the dump command, and update the
+appropriate reference positions.  This is done be defining an
+"atom-style variable"_variable.html, {check} in this example, which
+calculates a Boolean value (0 or 1) for each atom, based on the same
+criterion used by dump_modify thresh.  
+
+See the "compute displace/atom"_compute_displace_atom.html command for
+more details, including an example of how to produce output that
+includes an initial snapshot with the reference position of all atoms.
+
+Note that only computes with a {refresh} option will work with
+dump_modify refresh.  See individual compute doc pages for details.
+Currently, only compute displace/atom supports this option.  Others
+may be added at some point.  If you use a compute that doesn't support
+refresh operations, LAMMPS will not complain; dump_modify refresh will
+simply do nothing.
