Dear Justine,

if I want to restart my simulation (gromacs 3.3.3) do I need to re-define the "init" and " init_step" respectively.For example if I run my simulation for one nanosecond, is this the correct way to re-start again for another one second.

My .mdp file
==================================================
; Start time and timestep in ps
tinit = ???
dt = 0.002
nsteps = 500000
; For exact run continuation or redoing part of a run
init_step = ????
=================================================

what do I need to fill these XXX to make sure that I did not lose informations.

If you want to use grompp, then tinit corresponds to the start time of the new run, and likewise for init_step (the step that starts the new period of time).

It's probably far easier to just use tpbconv...
