[gmx-users] using old energies

[lorix]

Hi everyone,

I am simulating proteins in water at the equilibrium.
I try to run new simulations with a short protein (deleting atoms from 
the previous .gro file).
I understood that gromacs stores the atom velocities in the .gro file 
but also in the .edr file!
I would like to use the atom velocities coming from the previous 
simulation, but I need
to change number assigned to the atoms in the .top and in the .gro file.
Can I still use the velocities/energies from the previous .edr file?
If not, is there a way to feed the new .tpr file with the old 
velocities/energies if the system is part of the system has changed?


thanks in advance
