Dear all, 

I have been trying to obtain opls forcefield for small molecules.

I tried to follow the suggestions of previous gmx-users discussion


One possibility is to use the Schröedinger ffld server in combination with ffconv.py script to generate the topology.

Unfortunately the link for the ffconv.py link is expired and it is not possible to download it anymore.

Can someone please send me the script or mailing me the code?

Thanks a lot in advance.
