/* 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 hexorder/atom requires a pair style be defined
Self-explantory.
E: Compute hexorder/atom cutoff is longer than pairwise cutoff
Cannot compute order parameter beyond cutoff.
W: More than one compute hexorder/atom
It is not efficient to use compute hexorder/atom more than once.
