[AMBER] Cofactor GDP Atom Types

Dear Amber Users,

I have been using the force field modifications for polyphosphates
introduced by Meagher et al:

http://personalpages.manchester.ac.uk/staff/Richard.Bryce/amber/cof/phos_inf.html

And it worked fine. But when I wanted to do an MMPBSA calculation, it keeps
crashing because, it says, the radius of atom type O3 isn't available. As a
work around, I used parmed.py to change all O3's to O2's and the
calculation worked. The question is, is what I did by changing the type
right or wrong? And is there another way to just let MMPBSA accept O3 as a
type?

Thanks a lot..

Ahmed Ayoub
