[AMBER] Peptide with non-standard residues

Hi all,

I am trying to generate a peptide with three non standard residues: pGlu
(aka PCA) - His - Gly

I tried generating tha parameter files for PCA in antechamber and then
load it into leap.

Then I used the sequence command: sequence {PCA HIS CGLY}

Then I generated the peptide bond between PCA and HIS and removed the
resulting 2H and O.

I cannot save the parameter files of the resulting peptide, because
several bond, angle and torsion parameters are missing.

What's the best way to approach this? I could not find a tutorial where
this is described.

Kind regards,
