I am running g_helix on a run involving a 37 residue protein in the charmm force field. It has two long alpha helical segments. I have tried running g_helix with many different variations of commands and getting rid of PBC effects, but I always get the same error:
Checking group System There are 37 residues There are 0 complete backbone residues (from 0 to 524) ------------------------------------------------------- Program g_helix, VERSION 4.5.5 Source code file: /home/shared/installers/gromacs-4.5.5/src/tools/hxprops.c, line: 388 Fatal error: rnr==0 -------------------------------------------------------- Is rnr the number of peptide residues, or the number that are helical? In either case, nothing I do can seem to make it different from 0. -- View this message in context: http://gromacs.5086.n6.nabble.com/g-helix-not-recognizing-protein-backbone-tp4560173p4560173.html Sent from the GROMACS Users Forum mailing list archive at Nabble.com. -- gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting!
