[gmx-users] Viewing gromacs .xtc trajectory 'Error reading timestep, file does not match format'

[Mark Abraham]

Hi,

You can use gmxcheck / gmx check to examine the file and perhaps get some
more information, but this sounds like something has mis-managed your file.
e.g. you didn't construct it how you think you did, or the (parallel) file
system upon which you ran mdrun is not reliable.
