[AMBER] Some question regarding force field for periodic system

Dear Amber Users and Devs,
 

I have a novel sample of molecular crystal. Can I still parameterize the force field like the way we used on lipid? E.g. find the resp charge using Gaussian, and using antechamber and tleap. Should I load the molecular crystal in Gaussian as free molecule or confine it with PBC, will the conventional way of charge fitting methond will work on periodic system?

Regards
Min
