Re: [gmx-users] tpbconv subset
I modified the .mdp file, created a full system tpr, then ran it through tpbconv, then ran mdrun using the original xtc. It says the atom numbers don't match. mdrun -rerun md.xtc -v -s lig.tpr --- Program mdrun, VERSION 4.0.5 Source code file: md.c, line: 859 Fatal error: Number of atoms in trajectory (37655) does not match the run input file (65) --- On Sun, May 23, 2010 at 5:16 PM, Justin A.
