No I need your help in any way, antechamber is not only the way I could do
it, I think...I just showed you that I tried something before I wrote you a
letter.  It is not necessary to use amber forcefield, but I don't think that
prodrg is a good choice for this task, though the only modification of the
residues in the peptide is acylation. But may be you know something! Thank
you very much?

If you're asking for antechamber help, you're on the wrong forum.
