Hi, I am trying to conduct a mm-pb/sa calculation on a protein-ligand
complex. The first snapshot seems ok and then I get this torus error and the
energies are getting crazy as follows:

 VDWAALS = ????????????? EEL = ????????????? EGB =
?????????????
 1-4 VDW = ************* 1-4 EEL = 1059.4847 RESTRAINT =
0.0000

Here is part of my input file. I hope anyone has the similar experience
before and would like to share. Thank you.

Regards,
