You may remeber that I tried unsuccessfully to get the partial charges with
Antechamber in Amber9 for a 500-atoms non-repetitive molecule. Prof Case, and
others, suggested, however, that, even if calculated, the partial charges would
be unreliable for such a large residue.
Is the new code intended to solve this question too?
At any event, do you plan to make the new code available? An when? I have
frequently problems of large ligands.
Thanks
