I'm not entirely certain what the journal is looking for: the average
(and SD) amount of violation? The average of the absolute value of the
zero-threshold violation amount? You can specify
noe.setShowAllRestraints(True) to get info on all restraints in the
.viols file. Then you can calculate whichever value required.
