There is more than one way to do this, but here's what I do: make a copy of
$AMBERHOME/dat/leap/cmd/leaprc.protein.ff19SB (or whatever protein force field
you want.). In the copy, remove the "addPdbResMap" section, which is the code
that converts terminal residues. Source that leaprc file instead of the
original one, then proceed as usual.

....hope this helps....dac
