GROMACS version: 2020.1
GROMACS modification: Yes/No

My MD job interrupted due to unexpected system shutdown. I tried to start the job from same point using command “mdrun -s md.tpr -cpi md.cpt -deffnm md -append”.

After this command, I am getting following error. Please suggest me how to overcome this.

Program: gmx mdrun, version 2020.1-Ubuntu-2020.1-1

Source file: src/gromacs/fileio/checkpoint.cpp (line 358)

Fatal error:

Checkpoint file corrupted/truncated, or maybe you are out of disk space?

It is possible that, as indicated, the checkpoint file is corrupted/truncated. You may be able to restart from the previous checkpoint file (md_prev.cpt).
