That works equally well. On second thought, this could've been done
entirely within ParmEd (walk through the dihedrals, zero-out all impropers,
and pass the structure to either the sander API or OpenMM). You could do
the same thing with both the Gromacs and Amber representations.
Ah well -- an idea if you need to do something like this again, in any case.
All the best,
Jason
