Yes we observed the same things, and we are working on this...

You could use R.E.D.-II
http://www.u-picardie.fr/labo/lbpd/RED/ to calculate
RESP charges for your 10 conf. or for each conf. taken individually...

There were similar questions about this topic in the AMBER mailing list. Do a
google search in the AMBER mailing list using 'RESP charge' & 'enantiomers'.
Enantiomers (and diasteroisomers) are not differentiate in LEaP (if they do
present the same atom/residue names).

Fitting is not averaging! But at the end of the RESP
calculations do we have to average the 10 charges?Because when we use LEaP,
we have only to work with one set of charges for the enantiomers! So, how
to procede after the calculation of the RESP charges of our 10
conformations?
Thank you very much
