thanks for the reply. How i can check the stability of integration? If i consider 2 first ns for equlibration, can I trust the rest results?

This may or may not produce stable integration, but at the very least certainly will require some time to be discarded as new equilibration. -Justin > > On Tue, Dec 11, 2012 at 10:55 AM, Bahar Mehrpuyan > <baharmehrpu...@yahoo.com>wrote: > >> hi gmx user >> >> I've done a production simulation with gen_vel= no, but in grompp I forgot >> that use .trr file of equlibration simulation for initial velocities, >> my question is how gromacs treats with initial velocities in this case? >> >> thanks in advance. >> -- >> 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.
