Andrew,
There is a tutorial on how to do this. Please go to

Subject: AMBER: Antechamber Charge Calculation Method
Hi
I am trying to create a set of charges for a small molecule
(around 140 atoms) with Antechamber. I can create the charge for the
molecule (with the required +1 charge), but my problem is that I need to
connect this molecule to a piece of DNA. When I delete a hydrogen from
the molecule to connect it the a DNA base pair, I end up with a molecule
with a fractional charge. How do I create a removable group for a
molecule that has a net charge of zero (for the atoms that are removed)
and how do i calculate the charges for the molecules.
