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

[Vidyalakshmi CM]

Dear All,

I am trying to visualize the gromacs output .xtc trajectory on VMD. I am
generating .xtc trajectory frames every 5 ps. The total simulation run time
is 24195 ps which should give me 4839 frames (without any skip). However,
when I load frames say 4000 to 4100, I get the error message 'Error reading
timestep, file does not match format'.

With a skip of 10, I find the trajectory loads only initial frames (~200
frames out of more than 480 which is expected).

I have used VMD for viewing .xtc trajectories previously and have never had
this issue previously.

Please help.

Thanks and Best Regards,
C.M.Vidyalakshmi
