Dear Mark,
Thank you very much for the reply.
To clarify , I have asked all the warning based questions to get
acknowledged with your expert opinion, apart from the manual based view.
According to your suggestion NPT with Position restraints is
messy,but still I have seen lots of manual/tutorial (including Bevans
Lab ) suggesting the position restraining of protein during NVT as
well as NPT. That is the reason I have followed the same. Please
clarify your view on this matter.
It depends. If you need to fix your volume significantly, then trying to
do so while using position restraints is somewhat asking for trouble and
you should either give up position restraints or start again and get the
volume closer to correct in the first place. (Those tutorials have
likely managed this issue for you in the background.) Otherwise, use a
different type of refcoord_scaling like the warning said. The existence
of this mailing list is no substitute for doing basic background reading
in (at least) the manual :-)
Mark
