ups, sorry... I did not read carefully this part of your email... If different
conformations are used, this makes the problem even more complex because
different orientations can be selected for different conformations... (With
R.E.D. version 2.0, this will be automatically handled...)

See Reynolds et al. JACS 1992 114 9075.
Now what are the charge differences you observed ? If they are above 0.1, the
problem could come from the RESP inputs themself...
