Hi Thomas, You can label the bonds with their length with this Python: from chimera import openModels, Molecule for mol in openModels.list(modelTypes=[Molecule]): for b in mol.bonds: b.label = “%.2f” % b.length() You can label atoms, bonds, and residues in this fashion, but there is no provision to label bond angles per se. If you meant torsion angles and wanted to add that to the bond label, you can get the floating-point dihedral value of four atoms with this code: import chimera dihed_val = chimera.dihedral(a1.coord(), a2.coord(), a3.coord(), a4.coord()) —Eric Eric Pettersen UCSF Computer Graphics Lab

Hello,
Is it possible to load a small molecule in Chimera and display all bond lengths and angle values, pretty much as you can do using labelopt option for the atom names? If not directly, could you please give me some hints about how to write a Python script to do it?
I thank you in advance for your help. Thomas
