Hi everyone,


please I have an important question:
When I continue my simulation, I do: tpbconv -s .tpr -extend    -s .tpr
mdrun -v -s .tpr -cpi .cpt -cpo .cpt -o .trr -c .gro -x .xtc -e .edr -g .log

At one point of my simulation, I had a problem, the directory that contains all my topology and parameter files has been deleted.

So does it affect my simulation? Does gromacs need the topology and parameters at each step or does it stock all of these in the .tpr file?


The .tpr file contains all the necessary coordinates, velocities, simulation parameters, and topology information. There is no repetitive reading from your .top file. So if you lost your .top, you can still run a simulation. Just don't lose your .tpr file, too...

Thank you

Carla
