/* 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: No values in fix ave/histo command

UNDOCUMENTED

E: Fix ave/histo input is invalid compute

Self-explanatory.

E: Fix ave/histo input is invalid fix

Self-explanatory.

E: Fix ave/histo input is invalid variable

Self-explanatory.

E: Fix ave/histo inputs are not all global, peratom, or local

All inputs in a single fix ave/histo command must be of the
same style.

E: Fix ave/histo cannot input per-atom values in scalar mode

Self-explanatory.

E: Fix ave/histo cannot input local values in scalar mode

Self-explanatory.

E: Compute ID for fix ave/histo does not exist

Self-explanatory.

E: Fix ave/histo compute does not calculate a global scalar

Self-explanatory.

E: Fix for fix ave/histo not computed at compatible time

Fixes generate their values on specific timesteps.  Fix ave/histo is
requesting a value on a non-allowed timestep.
