/* 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 snap requires a pair style be defined

Self-explanatory.

E: Compute snap cutoff is longer than pairwise cutoff

UNDOCUMENTED

W: More than one compute snad/atom

Self-explanatory.
