Hi Luis and others,

thanks for your comment. If I got Amber right the alln(or c).in contains
the N(or C)-terminus with the NH3+(or COO-) attached to all the
residue types and their are refered by the N(or C)-residue type:
NVAL (or CVAL) for example. That is the more common way to
do. After it seems that you can use the "protecting" residues (ACE/NME)
that give a neutral N(or C)-terminus, and you add them by adding the
residues ACE or NME in your sequence.

I want something different and idealy simplier. I want to neutralize the
termini by only adding a Hydrogen on the N-terminus Nitrogen or on
a C-terminus Oxigen. And that I did not find in the topology files.

I was wandering if somebody had generated the topology of those
termini. They are pretty common.

Thanks for your time

XAvier
