I have need to collect 100ns but I can collect only ~1ns (1000steps) per run. Since I dont have .trr files, I rely on .cpt files for restarts. For example,
grompp -f md.mdp -c md_14.gro -t md_14.cpt -p system.top -o md_15 This runs into a problem when the run gets killed due to walltime limits. I now have a .xtc file which has run (say) 700 steps and a .cpt file which was last written at 600th step. - To set up the next run I use the .cpt file from 600th step. - Now during analysis if I want to center the protein and such, /trjconv/ needs an .xtc and .tpr file but not a .cpt file. So how does /trjconv/ know to stop at 600th step? If this has to be put in manually, it becomes cumbersome. Thoughts?
