Dear Mark, Thanks for your answer. "Only if you asked for velocity information to be written to the trajectory, with nstvout"
Usually, I use the following lines in mdp files: nstxout = 1000 nstvout = 1000 nstxtcout = 1000 nstenergy = 1000 nstlog = 1000 But, I get only position of atoms in time steps using VMD while I need to the velocity values for each time in time steps. -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
