/* 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 centro/atom requires a pair style be defined

This is because the computation of the centro-symmetry values
uses a pairwise neighbor list.

W: More than one compute centro/atom

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