You are right, Justin. I simply incorporated the corresponding terms to the ions.itp file by relying on the definition types made for GROMOS and OPLS ffs.

I don't see how these definitions are "completely different." Use either of these sections (OPLS or GROMOS) in ions.itp as a guide and add the appropriate sections for AMBER96. Using the OPLS definitions will be most directly analogous in terms of how the atom types are defined. -Justin > > Thanks in advance > Ozge Engin > ================================= > Computational Science & Engineering > Koc University > _______________________________________________ > gmx-users mailing list gmx-users@gromacs.org > http://www.gromacs.org/mailman/listinfo/gmx-users > Please search the archive at http://www.gromacs.org/search before posting! > Please don't post (un)subscribe requests to the list.
