Antechamber first performs AM1 optimization to get Mulliken charges and
then does bond charge correction.
 
All the best

Subject: AMBER: AM1-bcc



        Can someone verify that the AM1 atomic charges (to which the
bond charge corrections are applied) used in Antechamber's AM1-bcc
charge fitting algorithm are in fact Mulliken charges from an AM1
calculation? If so, does Antechamber perform a single point calculation
on the inputted molecule, or does it do any energy minimization?

        Thanks!
