I meant sander8. There is no pb in previous versions of sander. If you
use sander8 and "igb=10", "cut" will not be used, just set it to zero in
case any memory allocation is invoked. A default _finite_ residue-based
cutoff (cutres) of 12 A, atom-based cutoff (cutnb) of 10 A will be used
for the pb simulation with cap.

Note that the current pb implementation does not support partial
solvation of a solute, i.e. cap on an active site of an enzyme only.
