Subject: GB simulation on protein
Dear all,
I tried to carry a simulation of a protein with the version 7 of Amber
using GB solvent representation (igb=1,
saltcon=0.1, offset=0.13, cut=50).
After only 1 ps of heating, some atoms began to have v > vlimit (even v
= NAN) and
the calculations stopped because shake cannot be accomplished (deviation
too large).
As I had no such problems carrying the simulation of the same protein
with explicit water molecules (same
protocol), I am wondering why my system crashed.
I suppose it is due to the GB solvent representation but I do not know
why.
Thanks in advance for your help,
Fabien
