Writing one for a force field-bearing file format *is*.  Adding a GROMACS parser that worked correctly took significant contributions from at least 3 different developers -- the other two of whom were much more familiar with it than me.  Validation is by far the hardest part.  So *by far* the easiest way to add a LAMMPS parser to ParmEd is to tie InterMol and ParmEd together at the API levels :smiley:.  In fact, I think it's probably the only approach that has a reasonable chance of success on a realistic timescale."}}
