Dear all. Since I am interested in finding the average angle, dihedrals in my system, I attempted to use g_angle, but then I realized I need to make index file using mk_angndx,
I issued the following: mk_angndx -s npt.tpr -n angle.ndx and then i used g_angle -f not.xtc -n angle.ndx -ov angle.xvg -noperiodic -type angle and then I get the following error: Fatal error: Error: no groups in indexfile How can my index file not have the groups in there? How can I go about fixing this Any insight can be appreciated Thanks, Xu Huang-- 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! * Please don't post (un)subscribe requests to the list.
