Dear All, Why some of the improper parameters in CHARMM27 FF are repeated with the middle atom types in a different order as in, e.g.
HR1 NR1 NR2 CPH2 2 0.0000 4.184 HR1 NR2 NR1 CPH2 2 0.0000 4.184 while some are not, e.g. HR3 CPH1 NR3 CPH1 2 0.0000 8.368 Best regards, Dawid Grabarek -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
