I don’t have my minimization.gro file instead i have my minimization.edr file ( I lost my gro file accidentally) so how can I extend my nvt simulation run time
because we have to give mini.gro input under -c.
Is there any other way?
If you have already got a .tpr file for the nvt equilibration you can use gmx convert-tpr (gmx convert-tpr - GROMACS 2024.3 documentation) to extend the simulation time.
If you need to (re)generate a .tpr file, however, you will need the coordinates (confout.gro) from the energy minimization. However, running energy minimization is usually relatively quick.
Thank you
