ERROR: Invalid atom style (…/atom.cpp:374)

invalid XXX_style typically means that either you have made a typo, or
that you are trying to use an optional feature that was not installed
when compiling your LAMMPS executable. the latter can be easily
checked using the -h flag.

please also always consult
http://lammps.sandia.gov/doc/Section_errors.html before posting
questions about error messages. many frequently asked questions are
answered there already (not to mention checking out the mailing list
archives).
