Hi:

1st Question: prepin/frcmod (for an organic compound containing
covalent chlorine), coming from Antechamber in AmberTools1.2 are not
accepted by leap:

Atom .R<AA1 ###>.A<CL ##> does not have a type.

I guess that leap expects "Cl" for chlorine.How to arrange so that
Antechamber prepares files accordingly?
========

2nd Related Question: As the protein for the above complex (coming
from work up with Chimera) has atom names with four
characters/numbers, are, for example,

1C21
RH11

accepted by Amber10/AmberTools1.2, or should they be edited to


C211
H11R

as it was the case with Amber9?

Thanks
francesco pietra
