Dear all, I am trying to make a figure using ChimeraX to show the contents of the unit cell in one protein structure. I would like to show the cell box with the asymmetric unit (similar to that box obtained in chimera using “Tools>Higher Order Structure>Crystal Contacts” ) but ChimeraX apparently doesn’t recognize the command returning the following message in the log window: unitcell outline Unknown command: unitcell What I’m doing wrong? Is it the right command to show the box? Thanks in advance, Diego

Hi Diego, Sounds like you need to get a newer version of ChimeraX. With questions like this, you should say what version you are using (or first try getting a new version in case what you have is old). Command "unitcell outline" works for me in recent builds, <https://rbvi.ucsf.edu/chimerax/docs/user/commands/unitcell.html> ... and the Change Log says that this command was added in March 2021, so you need ChimeraX production release 1.2 or newer. <https://www.rbvi.ucsf.edu/trac/ChimeraX/wiki/ChangeLog> We just put a release candidate for version 1.3 on the download page, so you might want to try that one instead for even more features! I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Thanks Elaine, your are right, my version was not updated. I have installed version 1.3 and everything is working fine. Thanks! Diego
