We wrote the RED/XRED programs (see
http://www.u-picardie.fr/labo/lbpd/RED/)
allowing to get highly reproducible RESP/ESP charges whatever is the QM prog.
used (using Gaussian or GAMESS as examples) and whatever the starting structure
is (We plan to release RED/XRED next october). I guess it should be very simple
to apply our strategy using other QM soft such as NWCHEM or Spartan.
