/* 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 gyration/molecule requires molecular atom style
Self-explanatory.
E: Molecule count changed in compute gyration/molecule
Number of molecules must remain constant over time.
