You might be interested running R.E.D. Server Dev./R.E.D. Python at

R.E.D. Python will perform RESP or ESP charge derivation.
Different models are available:

R.E.D. Python performs many other tasks see:
among them: atom name corrections, atom typing and force field (FF)
parameter determination.

In your case known FF parameters will be reported in a frcmod.known
file, while unknown FF parameters will be listed in a frcmod.unknown
file. The later file will help you to determine which parameters you
need to work on.

R.E.D. Server Dev. can also accept as input a frcmod.user file, which
can be used to provide unknown FF parameters to R.E.D. Python.

regards, Francois
