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: Numeric index is out of bounds

A command with an argument that specifies an integer or range of
integers is using a value that is less than 1 or greater than the
maximum allowed limit.

U: Expected floating point parameter in input script or data file

The quantity being read is an integer on non-numeric value.
