/* ERROR/WARNING messages:

E: No dump custom arguments specified

The dump custom command requires that atom quantities be specified to
output to dump file.

E: Invalid attribute in dump custom command

Self-explantory.

E: Dump_modify format string is too short

There are more fields to be dumped in a line of output than
your format string specifies.

E: Could not find dump custom compute ID

The compute ID needed by dump custom to compute a per-atom quantity
does not exist.

E: Could not find dump custom fix ID

Self-explanatory.

E: Dump custom and fix not computed at compatible times

The fix must produce per-atom quantities on timesteps that dump custom
needs them.

E: Could not find dump custom variable name

Self-explanatory.

E: Region ID for dump custom does not exist

Self-explanatory.

E: Threshhold for an atom property that isn't allocated

A dump threshhold has been requested on a quantity that is
not defined by the atom style used in this simulation.

E: Dumping an atom property that isn't allocated

The chosen atom style does not define the per-atom quantity being
dumped.

E: Dumping an atom quantity that isn't allocated

Only per-atom quantities that are defined for the atom style being
used are allowed.

E: Dump custom compute does not compute per-atom info

Self-explanatory.

E: Dump custom compute does not calculate per-atom vector

Self-explanatory.

E: Dump custom compute does not calculate per-atom array

Self-explanatory.

E: Dump custom compute vector is accessed out-of-range

Self-explanatory.

E: Dump custom fix does not compute per-atom info

Self-explanatory.

E: Dump custom fix does not compute per-atom vector

Self-explanatory.

E: Dump custom fix does not compute per-atom array

Self-explanatory.

E: Dump custom fix vector is accessed out-of-range

Self-explanatory.

E: Dump custom variable is not atom-style variable

Only atom-style variables generate per-atom quantities, needed for
dump output.

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: Dump_modify region ID does not exist

Self-explanatory.

E: Dump modify element names do not match atom types

Number of element names must equal number of atom types.

E: Invalid attribute in dump modify command

Self-explantory.

E: Could not find dump modify compute ID

Self-explanatory.

E: Dump modify compute ID does not compute per-atom info

Self-explanatory.

E: Dump modify compute ID does not compute per-atom vector

Self-explanatory.

E: Dump modify compute ID does not compute per-atom array

Self-explanatory.

E: Dump modify compute ID vector is not large enough

Self-explanatory.
