Hi ChimeraX Users, Over the holiday, I wrote a package that will let you use the command line from Emacs, leveraging ChimeraX’s rest server. https://github.com/zjp/chimerax-emacs This should be helpful if you use Emacs as your main editor and you want to debug your bundles without leaving your editors. Contributions from other emacs users welcome. — Zach

Doubt about sequence visualization after real.space.refinement in phenix
by Leyre Marin Arraiza 04 Jul '24

04 Jul '24

Dear UCSF ChimeraX, I have a practical question regarding model sequence visualization after real.space.refinement in phenix. After I worked on my model in ISOLDE and Coot, I deleted some residues that were out of the map density. Then, a dashed line appeared in my model, connecting the gap between the remaining residues (example, ALA97------GLN110). When I visualize the model sequence in ChimeraX, the deleted residues appear boxed with a rectangle, to indicate they are missing in the structure. Once I get the results back from the phenix real.space.refinement, and I visualize the model sequence in ChimeraX again, the deleted residues do not appear boxed anymore, but they are gone instead from the visualized sequence, keeping their corresponding numbers but not showing a boxed gap (in the example I mentioned they jump from 97 to 110 directly). I would like to keep the deleted residues boxed in the sequence when I visualize it. Is that possible? Hope I am explaining myself.

show 5% or 10% Z-axis of a fibril density
by Binh Nguyen 04 Jul '24

Dear all, Is there a way to display say 10% on the Z-axis of a fibril density map? Or maybe save 1 or 2 layers of the map? [cid:11c579f0-867a-4136-b817-27e4c071e57e] I know 2 ways to do it but they both take a long time, and I wonder if we have an easier way to do it. 1. Use volume eraser with a big diameter sphere 2. Build a rough backbone carbon model in 1 layer, and do zone selection. Thanks, B ________________________________ UT Southwestern Medical Center The future of medicine, today.

Doubt about chimera
by DIEGO ANGOSTO BAZARRA 03 Jul '24

03 Jul '24

Hello, My name is Diego. I’m a beginner user of ChimeraX (1.8) and I was wondering if there is an option to check the % of similarity between two structures after making the matchmaker. I mean, I make a matchmaker with two structures, can I see the % of similarity between these two structures? Not between the sequences, but between the structures. Thank you very much for your time and attention. Best regards Dr. Diego Angosto Bazarra Molecular inflammation and experimental surgery group. IMIB. University Hospital Virgen de la Arrixaca

ChimeraX workshop
by Jisoo Hwang 03 Jul '24

03 Jul '24

To whom it may concern, Good afternoon! I hope this email finds you well. I'm a student doing research at Johns Hopkins and was wondering if it'll be possible for us to set up a zoom meeting to ask some questions about the software. It's my first time using the software and it would be incredibly helpful if we can have a short workshop going over the features of ChimeraX. We're trying to include a 3D structure in a paper that we're planning on publishing soon. Please let me know if there's any other resource that you can point us to if we can't do a zoom meeting. Thank you so much for your help! Best, Suzie Hwang
