[chimera-dev] Changing guide atom

Hello list,

I'd like to change the guide atom in res.ribbonData to use
O instead of CA as an example.
Here is what I did:

for r in mol.residues:
  for a in r.atoms:
    if a.name == 'O':
      r.ribbonData.guide = a		# Set O as guide Atom
      if r.isHelix: 			# Update the display 
	r.ribbonDisplay = True
	r.ribbonDrawMode = chimera.Residue.Ribbon_Round

This does not seem to redisplay/recompute the helix through O Atoms.

I am not confident with the way I altered the guide Atom or is it
another problem like updating the ribbon or so...
If someone can help...

Thanks to all
