Dear gromacs-users,

                                     I want to run simulation of system of
peptide with carbon nanotube. And I want to run multiple simulations for
the same initial structure using different random initial velocities. For
that which values I have to use in the case of gen_seed=-1. Instead of -1
which values Can I use for gen_seed? is there any other way to assign
different random velocities.

gen_seed takes any integer as a value. Using -1 is typically fine for just about everything, unless you need a record of exactly which seed was used (but that's printed to mdout.mdp and md.log, anyway).
