I think this problem is not due to the disk space cause I check that it has a large space in the fold. I have tried some times but always the same results ,no trajectory files while the others are normal .
Thank you very much for your reply. Yang ________________________________________ From: [email protected] [[email protected]] On Behalf Of Justin A.

That might indicate a problem with available disk space, depending on how large the file is. -Justin > ; RUN CONTROL PARAMETERS = > integrator = md > ; start time and timestep in ps = > tinit = 0.0 > dt = 0.03 > nsteps = 1000000 > ; number of steps for center of mass motion removal = > nstcomm = 1 > > > ; OUTPUT CONTROL OPTIONS = > ; Output frequency for coords (x), velocities (v) and forces (f) = > nstxout = 5000 > nstvout = 5000 > nstfout = 0 > ; Output frequency for energies to log file and energy file = > nstlog = 1000 > nstenergy = 1000 > ; Output frequency and precision for xtc file = > nstxtcout = 1000 > xtc_precision = 1000 > ; This selects the subset of atoms for the xtc file.
