Hello all,
I am having a very difficult time with PBC conditions for a protein
complex. I am attempting to take some minimized coordinates from the
protein + box and do simmulated annealing. I know that the box
coordinates can change (in constant P situations) and I think this is
the case. As soon as I start the simmulated annealing, my protein is
distorted, and I'm guessing it has to do with the transfer of box
coordinates. The box coordinates from the topology file and the
minimization output are the same. Here's my input, let me know if you
can help.
Thanks,
