MUNKI Managed Software Download URL
by Antony Nelson 14 Feb '25

14 Feb '25

Hi, I appreciate this might seem an odd request, but do you have a public download location for ChimeraX software? There exists a widely used system by which administrators of Apple computers distribute software to their users by means of applications known as Munki and Autopkgr. Software which can be downloaded from public websites can be managed in such a way that new releases and updates are automatically added to the software repository Apple administrators curate for their users. Without making this publicly available, admins will only update your software when users request the admins to do so. Looking back on the Loupe Browser instances that have been made available to my users, they have only had access to versions: 0.8.0 0.9.0 0.9.1 0.93.0 1.1.1 1.7.1 and today they will have 1.9.0 If your software was made available via public download by a predictable URL, then they would have had access to every version released on the day it was added to your website since it was first requested by users. If you are concerned about the acceptance of terms of conditions then perhaps this could be incorporated into the URL string. Regards

Hi there, I am trying to create a video with two maps overlay with different silhouette widths. It is easy to do with 2 images, but how I can do it in a video setting? If I change the width to 6, all maps changes the width to 6. Thanks! -Hong

Unable to load scripts at startup
by Pranav Shah 13 Feb '25

13 Feb '25

Hi Team, (I accidentally sent this to ChimeraX-bugs, copying it again here) I am trying to load some scripts at startup via the chimerax_custom_functions.cxc command file - open /Users/ps/.chimerax/chimerax_commands/chimerax_custom_functions.cxc in the log file I see the following message: still retrieving bundle list from toolshed open /Users/ps/.chimerax/chimerax_commands/chimerax_molmap_cube.py Error running startup command 'open /Users/ps/.chimerax/chimerax_commands/chimerax_custom_functions.cxc': Unknown command: open /Users/ps/.chimerax/chimerax_commands/chimerax_molmap_cube.py This is strange as simply running "open /Users/ps/.chimerax/chimerax_commands/chimerax_molmap_cube.py" in the ChimeraX command panel runs perfectly fine! the error occurs only when I try to run that line through the .cxc file. Am I missing something? or could this be a bug? I am on the stable release of ChimeraX (version 1.9). Best, Pranav -- Pranav Shah Postdoctoral Research Fellow.

PAEcontacts colorkey
by ccinsua＠gmail.com 13 Feb '25

13 Feb '25

Hi all, Thank you very much for your work with chimerax. I've been using it to study alphafold complex prediction, and I find the command alphafold contacts very useful. The default color key (guess it is paecontacts, according to documentation) ranges are blue (low PAE) - green (medium PAE) - yellow (high PAE). However, I am unable to add a color key using "key paecontacts". Somehow I have to define it myself. Is there anything I am missing? I would like to stick to the blue-green-yellow scheme. Thanks a lot in advance Carlos

ChimeraX fetch by PubChem CID

Hi Alexander, The recommended address for asking ChimeraX questions is the chimerax-users(a)cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu> mailing list CC'd here, see "contact us" on our website or in the ChimeraX menu: <https://rbvi.ucsf.edu/chimerax/docs/contact.html> If PubChem Compound has the coordinates, you can open them in ChimeraX by CID, e.g. command open pubchem:12123 - OR - open 12123 from pubchem ... as explained here <https://rbvi.ucsf.edu/chimerax/docs/user/commands/open.html#fetch> ...or with menu: File... Fetch by ID, choosing the Pubchem option and specifying the CID in the dialog: <https://rbvi.ucsf.edu/chimerax/docs/user/fetch.html> However, not every entry in PubChem Compound has coordinates available, so I don't know if it will work for your specific molecules of interest. I hope this helps, Elaine ----- Elaine C.
