Subject: [AMBER] query about the charge fitting procedure about C- and N-terminal residues

Dear Amber developers,

Recently, I noticed that the atomic charges of N-terminal residues differ
a lot between ff94 and ff03. In ff03 paper, I only found explanation for
the fitting procedure for non-terminal residues. So I am wondering how
the atomic charges were fitted for C- and N-terminal residues. Can
anyone tell me?

best regards,
