Subject: Re: AMBER: ff02 force fields

Hello,

Thank you very much for your answer. But I have another question.

I want to obtain the new set of atomic charges for using ff02 in a
different molecule (different to aminoacids). How do I obtain this new
set of charges? or which is the procedure to obtain this new set of
charges for my molecule for using with the ff02 force field?

Many thanks,

Castillo
