Hi, I am running a sander.MC calculation of protein/ligands interactions with
10 ligands . My calculation can't go through. My input file and output are
at the end of this email (ligands are in residence #288 to 297). The
sander.MC refuse to calculate electronic related energy and the DEVIATION IS
TOO LARGE. It seems to me sander.MC can't treat the 10 ligands in the MC
region right. Please give me a example of your input file if you have the
experience with sander.MC. Thanks in advance.
