Thanks. Problem solved now.

I saw that, but it is coming from discrepancies between naming conventions in
certain PDB : sometimes the name is C7, sometimes C5M (and so is for the
protons names 1H7 or 1C5M).

I'm sure i can trust you, but as protonate was recommended in AMBER6's
tutorial, in this particular situation ...
