Hi Eric, thanks. No problem at all. I will eventually use the Python shell, but for the moment I am content with communicating via REST, which works just fine for visualization purposes. I justed wanted to know what I can and cannot implement in this interface.

Hi Gunnar, The setattr command can't do this. It would not be too hard to add it to setattr, but it doesn't seem to be something anyone would commonly want to do, though I'm willing to listen to arguments otherwise. This is pretty easy to do in ChimeraX's Python shell though (Tools→General→Shell). The following code (typed/pasted) to the shell would set all selected atoms' coordinates to 1,2,3: from chimerax.atomic import selected_atoms as sel_atoms for a in sel_atoms(session): a.coord = (1, 2, 3) If you're not familiar with Python, indentation is significant, so that last line needs to be indented as shown. --Eric Eric Pettersen UCSF Computer Graphics Lab On Oct 23, 2020, at 12:52 AM, Jeschke Gunnar <gunnar.jeschke@phys.chem.ethz.ch<mailto:gunnar.jeschke@phys.chem.ethz.ch>> wrote: Hi all, is there a way to set atom coordinates by a command? setattr spec atoms coord value appears to accept only one double argument and sets x, y, and z to this number.
