1. Use the Amber FF files instead. (Requires some hand editing of the PDB file.) 2. Also build in my modifications to gromacs 3.3 from here http://saf.bio.caltech.edu/pub/software/molbio/gromacs-cit-33.tar.gz and you can probably just run your input PDB file through pdb2gmx using the Amber FF with no hand editing required.
