Re: [Chimera-users] Saving symmetry model in pdb format
by Elaine Meng 17 May '24

17 May '24

Hi Kailash Singh Bisht, You sent the message to chimera-users which is for Chimera questions. However, you said "ChimeraX team" so I am guessing that you are actually using ChimeraX, and I CC'd the chimerax-users address above -- please use that one for ChimeraX questions. You didn't say how you created the symmetry structure. I am guessing that when you create the symmetry structure with the "sym" command, you need to include the option "copies true" so that you get real atomic copies instead of just graphical clones. <https://rbvi.ucsf.edu/chimerax/docs/user/commands/sym.html> <https://rbvi.ucsf.edu/chimerax/docs/user/commands/sym.html#copies> I hope this helps, Elaine ----- Elaine C.

prediction of 5mC modification and transcription factor interaction through AlphaFold 3
by Kaan Okay - HI 17 May '24

17 May '24

Hi, I use Alphafold through UCSF ChimeraX. It is a very nice tool, I believe its developers have done a good job. As you know, AlphaFold 3 is a new model that allows us to predict DNA modification and protein interactions (https://www.nature.com/articles/s41586-024-07487-w) What I wonder is when this model will be transferred to UCSF ChimeraX and whether we can predict protein interactions and DNA modifications (e.g., 5mC modification on cytosine bases in DNA). I'm looking forward to hearing from you. All the best.

Cinematographic effects in MD movie recording
by Enrico Martinez 17 May '24

17 May '24

Dear Chimera-X users ! I would like to add some cinematographic effects such as changing the camera angle back and forth during a short recording time of MD movies. Could you suggest some scripting tricks that I could add to the following coordset routine: # start recording movie record size 3840,2160 supersample 1 ## play movie from beginning to the end coordset #1 1,1000,1 wait 1000 etc Would it be possible to bend the camera automatically e.g. during the first 250 steps of recording ? Any other possibilities ? Yours with thanks Enrico

Displaying angles in chimera
by Prathvi Singh 16 May '24

16 May '24

Hi Elaine, Is it possible in chimera/chimeraX to display angles between two covalent bonds like in pymol? -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016

"H-Bonds" Tool Displays Non-H Bond Bonds?
by Melisa Kalaba 15 May '24

15 May '24

Hello. I wanted to display the hydrogen bonds between my ligand and protein, however when I hovered over the displayed bonds with my cursor I noticed one of the bonds being between two nitrogen atoms and I was confused. Is this a bug within the software? I'll attach a screenhot so you can take a look at it yourself: https://drive.google.com/file/d/1N5YRncOrrJnEVRpM8XD7O1tPG02ZTu8G/view?usp=…

Missing-structure labels
by Eric Pettersen 15 May '24

15 May '24

Hi all, In the 1.9 daily build only (not the 1.8 release candidate), missing-structure pseudobonds are now labeled with the number of residues the pseudobond represents. If you do not like this new behavior, you can turn it off in the 'Labels' preference category (make sure to 'Save' your changed setting). --Eric Eric Pettersen UCSF Computer Graphics Lab

Alphafold3 models
by Allen Place 15 May '24

15 May '24

I just ran Alphafold3 predictions on our dinoflagellate pks proteins. Will chimerax read the models which are .cif files? I want to highlight the various domains in the 3D models. I am running on OSx. Al Allen R.

Cofr command output in log
by Kumpula, Esa-Pekka 14 May '24

14 May '24

Dear ChimeraX crew, A minor quality-of-life improvement request: would it be possible to have the command cofr output the values as a comma-separated list instead of a whitespace separated one? I am including cofr information reatively often in my figure preparation scripts and having NOT to always replace these when copy&pasting would be a nice improvement! Also, in general, can I customize the output of commands to the log (such as view matrix, cofr, zoom, clip list) within an alias for example? In a fluffy dream world, I would have an output from these that I can directly copy&paste to my scripts and get the camera positioned Just Right.

Feature request for .glb files
by Leonardo BETANCURT ANZOLA 14 May '24

14 May '24

Hello! I am currently exporting .glb files so I can add them to a Keynote presentation and would like to keep the labels for the amino acids. When I see the file, the letters are in 2d, do you know if there is a way to add a little bit of depth to the letters when exporting such a file? I added a video that shows how the labels are invisible from some points of view Also, it would be awesome if files could be exported in .usdz so they can be easily added to Keynote Thank you, Leo B

Fwd: Inquiries on UCFS Chimerax
by Tom Goddard 14 May '24

14 May '24

Please send ChimeraX questions to the mailing list unless they contain private data. Begin forwarded message: From: ahmed morsy Subject: Inquiries on UCFS Chimerax Date: May 7, 2024 at 4:52:22 AM PDT To: "goddard(a)cgl.ucsf.edu" Reply-To: ahmed morsy Dear Dr. Thomas Goddard, I hope this message finds you well. I am very thankful for your great tutorial on the UCFS Chimerax YouTube channel. I have a few questions that need your kind response: 1- Can we apply UCFS Chimerax for detecting the interaction between protein & ligand, or small molecule (from Pubchem library) and protein? 2- What is your standard for increasing or decreasing C-alpha distance (in Angestrom) to color the structure that is different between the Alphafold prediction and the experimental one? Thank you for reading my message, and I look forward to hearing from you.
