/* 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: Cannot use compute cluster/atom unless atoms have IDs
Atom IDs are used to identify clusters.
E: Compute cluster/atom requires a pair style be defined
This is so that the pair style defines a cutoff distance which
is used to find clusters.
E: Compute cluster/atom cutoff is longer than pairwise cutoff
Cannot identify clusters beyond cutoff.
W: More than one compute cluster/atom
It is not efficient to use compute cluster/atom more than once.
