Dear Amber members,

I'm confused about some parameters:
 1. <entry name="NA" element="N" hybridization="sp2" description="sp2 N in 5 memb.ring w/H atom (HIS)"/>
    <entry name="NB" element="N" hybridization="sp2" description="sp2 N in 5 memb.ring w/LP (HIS,ADE,GUA)"/>‍

I found those in /mtkpp/parm94.xml. I really dont understand "w/H" and "w/LP".(I guess NA has a H atom,and NB doesn't)

2.
Zinc(II) Ion ZN1 INT 1 CORR OMIT DU BEG 0.00000 1 DUMM DU M 0 -1 -2 0.000 .0 .0 .00000 2 DUMM DU M 1 0 -1 1.449 .0 .0 .00000 3 DUMM DU M 2 1 0 1.522 111.1 .0 .00000 4 ZN ZN M 3 2 1 1.000 90.000 180.000 0.90949 DONE‍ I want to get a file like that for my copper ions,but I just find one for zinc.Where can I find explanations of those parameters?

Look forward to your reply!
Best wishes.
