Long story short: backup everything (since it's a backup, and hopefully
you won't need it), then use the [whatever].cpt file. You don't want to
do work twice, do you? If you use the [whatever]_prev.cpi file, you will
calculate some frames *again* that are already there.
If you use an up-to-date version of Gromacs (4.5.5 is the most recent
one), then the files will be continued and not overwritten. This is
stated on the page you already found (hint: "remaining output will be
appended to the existing files (energy, trajectory, log, etc).")
Good luck,
Matthias

Hello all,
I am going to restart my crashed simulations, but I am not sure which
of *_prev.cpt or *.cpt to use as they contain different written
frames.
*_prev.cpt >>>> Last frame -1 time 7462.900
*.cpt >>>> Last frame -1 time 7468.965
Also on the gmx site it is stated that :
Before doing anything, back up your files! Then use
mdrun -s topol.tpr -cpi state.cpt
What files do I need to back up? the edr. trr .. files that were
written before crash? Is the new run going to overwrite the old files?
Thanks,
