/* 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 cna/atom requires a pair style be defined

Self-explanatory.

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

Self-explanatory.

W: Compute cna/atom cutoff may be too large to find ghost atom neighbors

The neighbor cutoff used may not encompass enough ghost atoms
to perform this operation correctly.

W: More than one compute cna/atom defined

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

W: Too many neighbors in CNA for %d atoms

More than the maximum # of neighbors was found multiple times.  This
was unexpected.

W: Too many common neighbors in CNA %d times

More than the maximum # of neighbors was found multiple times.  This
was unexpected.
