/* 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 chunk/atom stores no IDs for compute property/chunk

It will only store IDs if its compress option is enabled.

E: Compute chunk/atom stores no coord1 for compute property/chunk

Only certain binning options for compute chunk/atom store coordinates.

E: Compute chunk/atom stores no coord2 for compute property/chunk

Only certain binning options for compute chunk/atom store coordinates.

E: Compute chunk/atom stores no coord3 for compute property/chunk

Only certain binning options for compute chunk/atom store coordinates.

E: Invalid keyword in compute property/chunk command

Self-explanatory.

E: Chunk/atom compute does not exist for compute property/chunk

Self-explanatory.

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

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