Hi Xavier, No, there's no command line equivalent, nor is there any real plan to add one soon. Therefore you would have to resort to using a Python script. It would be a fairly simple script though. For example, to make a smooth worm whose radius is equal to the residue's MAVconservation attribute + 0.25, it would be something like: from chimera import openModels, Molecule, RibbonStyleWorm, Residue for m in openModels.list(modelTypes=[Molecule]: for r in m.residues: conserve = getattr(r, "MAVconservation", None): if conserve is None: continue r.ribbonDrawMode = Residue.Ribbon_Round r.ribbonDisplay = True r.ribbonStyle = RibbonStyleWorm(conserve + 0.25) You would put the above in a file ending in .py (e.g. "worm.py") and run it simply by opening it with the "open" command. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Jul 1, 2015, at 1:15 AM, Xavier ROBERT <xavier.robert@ibcp.fr> wrote:

Dear all,

I am wondering if there is a way to call "Render by Attribute" at the command line in order to render a worm representation? If not, is this feature planned for the near future and is there any workaround for this?

Thank you very much in advance. Kind regards, Xavier R.
