Hi Justin, Thank you very much for your reply. I would try also position restrain instead of freezing. But it is still strange to me why I got average pressure of 1 bar after running only for 5 ns for the completely frozen finite DNA when I did isotropic pressure coupling. But for the infinite frozen DNA with semi isotropic pressure coupling it shows problem.
Thank you very much, Regards, Arnab -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
