Re: Could I do the equilibration again with the same dcd file obtained?

short answer: no

longer answer:
even if you had the restart files and the correct seed,
due to thermostats, barostats parallel computing etc., you
will not be able to reproduce exactly the same trajectory.
I think this data is lost.
