Hi Enrico,
This is actually quite simple, see the PyMOL wiki:
https://pymolwiki.org/index.php/Aa_codes
Paste this python dictionary into PyMOL:
one_letter ={'VAL':'V', 'ILE':'I', 'LEU':'L', 'GLU':'E', 'GLN':'Q', \
'ASP':'D', 'ASN':'N', 'HIS':'H', 'TRP':'W', 'PHE':'F', 'TYR':'Y', \
'ARG':'R', 'LYS':'K', 'SER':'S', 'THR':'T', 'MET':'M', 'ALA':'A', \
'GLY':'G', 'PRO':'P', 'CYS':'C'}
The one letter codes can be accessed with one_letter[resn]
To do something like Y-119:
label sele, '{}-{}'.format(one_letter[resn], resi) # front end command
cmd.label('sele', "'{}-{}'.format(one_letter[resn], resi)") # backend command
Cheers,
Ali

exactly we may do it in the context meny for the particular selection
(we do not need to select a particular residues, so ..)
but may we create the same label using label command as well ??
cmd.label('sele', 'resn')
I think something should be used instead of 'resn'. there is also
option 'resi' which shows only the number of the amino acid. So I need
to combine "resn" and "resi"
:-)
