Hi
I am trying to run cpHMD for a non-standard molecule. I find it hard for
finddgref.py to converge and the fraction of protonation % is very
fluctuating (1 million equillibration steps) . My residue is pretty large
( about 120 atoms ) as it is a side chain of a carbohydrate polymer
Any strategy for fast convergence ?
