Dear Amber users,
I am facing a problem with restraints on Amber 9. I am using cartesian
restraints (ntr=1) with this sort of mask:
restraintmask = '(:112 >.8.0) :1-111!.H'
I tried to do some MD with this sort of restraint in explicit solvent.
Generally, I share my simulation in several runs (generaly 100ps). When I do
these simulations in NVT I have no problem (ntb=1). However, if I launch the
same simulation in NTP, my restraint energy always begins with a huge value
on every starting runs. I don't have this problem if I don't share my
trajectory into several runs. Therefore, I think my problem arises from the
reading of coordinates when the non-bonded atom list is created. Is there any
people who have an idea how to solve my problem?
Best regards
Florent Barbault
