Dear users,

I have a corrupted .xtc file.
I can read only part of the whole frame in VMD.
When I gmx check  the .edr file, there is no problem with 5001 frames.
However if I do gmx check the .xtc file, then I get only 2954 frames out of
50001 frames.

I used Gromacs 2019.6 with CUDA on a single node.
I saved only xtc, edr, gro, cpt and log files.
In addition, I  cannot SCP the file to another machine.
By a bash script (with PBS pro), I have run the simulation until
md1.part0020.xtc without any problem.

Is there a way to recover the xtc file?

The following is the output from gmx check.
