Dear All,
by mistake, I have overwritten the *.cpt file. Is there any way I can continue the simulation from the last point?

Hi,

if you have a trajectory with velocities you can create a new .tpr file from its last frame. Use gmx grompp -t [trajectory] [other options]. This will be considered a new simulation so be sure to keep track of your old output files.

If you did not overwrite the *_prev.cpt file, you can continue from it instead.
