/* 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: Chunk/atom compute does not exist for compute fcm/chunk

Self-explanatory.

E: Compute fcm/chunk does not use chunk/atom compute

The style of the specified compute is not chunk/atom.
