Hi Jerome, thanks a lot for pointing out. I think I have always been
trying to look for the answer from the "NAMD tutorial", or otherwise
googling my question, such as "NAMD and damping coefficient" etc. I
actually didn't pay attention to "NAMD 2.6 user's guide". I will look it
up next time.Boyang.
