Thank for your instant reply. I've copy the topology description into .rtp file, and update the residuetypes.dat file, pdb2gmx didn't show any message about residue recognition problem, so I think gromacs accepted my new residues.
so, I think the only way is to add new terminal entry for nucleotides, I'll share the file if I success. Thanks anyway =) Daniel -- View this message in context: http://gromacs.5086.n6.nabble.com/Nucleotide-terminal-problems-in-GORMOS96-force-field-tp5001965p5001967.html Sent from the GROMACS Users Forum mailing list archive at Nabble.com. -- gmx-users mailing list [email protected] http://lists.gromacs.org/mailman/listinfo/gmx-users * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting! * Please don't post (un)subscribe requests to the list.
