Hi Maiti,
You haven't given your fellow NAMD users much information to go on here in
order to help you. Perhaps if you sent us a copy of your NAMD config
scripts (one with NPT and the later one using NVT) that would be a good
start.
The first thing that occurs to me is that you might have specified an
incorrect box size for your NVT run; perhaps you used the initial system
size (from before it was changed by your long constant-volume run) by
mistake? What were the dimensions of your MD box before and after your NVT
run? (This info will be in your *.xst output file.)
regards,
Erik
