Hi everyone,

I have a question and be thankful if you help me. As you know some of forcefiled can not support some of atoms(COMPASS ff for Pt). Would you please tell me is it possible to use  combination of COMPASS and manually inserted forcefiled(only for atom which can not be supported by COMPASS). It means that for all of atoms COMPASS ff and for the atom which unsupported by COMPASS, the new inserted forcefiled is used.

Best Regards
