I think it will be better if you build your residue SERINE-DEP with
the covalent bond in another program (for exambple insight or sybyl), and then
calculate the charges as indicated in the manual with antechamber.
If you want to have both DEP and SEH in separated residues, my guess is
that you have to define wich atom is head and/or tail in each one.
Hope this help,
