[gmx-users] gmxcheck : Magic Number Error in XTC file (read 0, should be 1995)

[Amit Kumawat]

Thank you very much David. Out of the complete trajectory I identified all
those frames which are corrupted and manually concatenated the rest of the
trajectory. Can you provide me suggestion for the possible source of error.
Because in the log file I could not see any out of disk space error and I
have been using the same version of gromacs  for initiating or extending
the simulation
