/* 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: Cannot use region INF or EDGE when box does not exist
Regions that extend to the box boundaries can only be used after the
create_box command has been used.
