Dear GMX users,
We want to develop the ff parameters for some small molecules in
consistent with gromos 53a6, and I know that PRODRG can do it, but it is
not accurate enough. So we want to do some QM calculations to validate
it. However, how can I derive these parameters for bonds and dihedrals
from QM calculations, and also the partial charge. In Amber, antechamber
can do it, so is there also such a tool for gromacs? Any suggestion will
be appreciated.

Before you do it yourself:
Check http://compbio.biosci.uq.edu.au/atb/ for gromos parameters
or http://virtualchemistry.org/ for OPLS/AA and GAFF alternatively
http://mackerell.umaryland.edu/~kenno/cgenff for the Charmm generalized FF.
