/* ERROR/WARNING messages:

E: Illegal ... command

Self-explanatory.  Check the input script syntax and compare to the
documentation for the command.  You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.

E: Compute aggregate/atom used when bonds are not allowed

UNDOCUMENTED

E: Cannot use compute aggregate/atom unless atoms have IDs

Atom IDs are used to identify aggregates.

E: Compute aggregate/atom requires a bond style to be defined

This is so that a bond list is generated which is used to find aggregates.

E: Compute cluster/atom requires a pair style to be defined

UNDOCUMENTED

E: Compute cluster/atom cutoff is longer than pairwise cutoff

UNDOCUMENTED

W: More than one compute aggregate/atom

It is not efficient to use compute aggregate/atom  more than once.
