Hi all: I'm trying to use the .cxc script to run the software, I found that the "surface dust" command has never been executed in it. Have anyone met the same problem? Any suggestions. Thank you all. Best, Ze

Double and Triple Bond Stick Style
by Smith, Chase 05 Feb '25

05 Feb '25

Dear ChimeraX, I was just wondering why there is no way to represent a double or triple bond in either the ligands or the protein amino acids when viewing as a Stick or Ball-and-Stick representation? I sometimes use Chimera or ChimeraX to make visuals for my lectures, and the students often have difficulty in understanding due to the absence of the multiple bonds. I would love to have the ability to represent the double or triple bonds with multiple lines between the atoms. Thank you, Chase Smith ...

Quest 2 Support?
by Blaine Hewitt 27 Dec '24

27 Dec '24

Hello, my name is Blaine Hewitt. Now I know that you have stated previously that you have no intention of bringing support to the Oculus Quest. Which is completely understandable since I know that not only would you have to develop around a completely new Operating System but another CPU architecture and much much more I assume. But with the soon release of the Oculus Quest 2 and it's new XR 2 chip-set makes a pretty good argument for it. As this would allow for much easier use in education (as is what I am attempting to do with it). I think it will be even easier now to push updates with SideQuest <https://sidequestvr.com/> being relatively simple to setup. I know that another (Naome <https://blog.matryx.ai/nanome-on-quest-public-beta-is-now-available-b546321…>) program is already available on the platform. But I do like your program a lot more since it is able to be used for free unlike Nanome Pricing <https://nanome.ai/pricing/> which is... as to say unappealing to public schools (such as mine). I was was also thinking (sorry if I am becoming annoying at this point) that if you do make a version of the Quest that you could make that GitHub branch available to the public. As for example while I may not be great at understanding complex protein structures I can help to make the whole experience more user friendly. Anyways if you read this far thank you for taking time from your day to read this. If you want to know who I am, my name is Blaine I am in my senior year of High School (Waynecsd <https://wh.waynecsd.org/>). I have to do a project by the end of the year where I have to present an area of study I want to pursue and I decided to research the effects of VR on the human's ability to learn and retain information. Budget..... None

Apple silicon (M1 chip) native version?
by Jeffrey D. Hartgerink 28 Apr '22

28 Apr '22

Are there any plans for an Apple Silicon (M1 chip) native version of ChimeraX? While things work ok via the Rosetta emulator, it would be great to have the performance from a native app. -------------------------------------- Jeffrey D.

Next/previous buttons?
by Oliver Clarke 07 Feb '22

07 Feb '22

Hi, The Next/Previous buttons in original Chimera, combined with the capacity to lock the display status of one model (using the "Skip") checkboxes, are really useful when comparing multiple maps (particularly multiple aligned maps with a single atomic model), and I really miss this functionality in ChimeraX... would it be possible to add it to the (diminishing!) list of features to port over? Cheers Oli PS My mind was blown yesterday when I found out that ChimeraX has (universal?) undo/redo bound to hotkeys! Would it be possible to add the option of user defined hotkeys...? E.g. for invoking a custom function, style, lighting etc?

How to open .py file downloaded from MOLEonline in ChimeraX?

Hello, I've been using Chimera in the past for opening downloaded .py files from MOLEonline to visualize tunnels in my structure. When I try to do the same in ChimeraX, I get the following error: Traceback (most recent call last): File "/Users/katekim/Downloads/mole_channels_6Qzq10eGEqLciv3DpeS8Q_1_chimera.py", line 1, in <module> import chimera, _surface, numpy ModuleNotFoundError: No module named 'chimera' Error opening python file /Users/katekim/Downloads/mole_channels_6Qzq10eGEqLciv3DpeS8Q_1_chimera.py toolshed show Any suggestions on the best approach to visualize MOLE channels using ChimeraX? Thank you, Kate

Making multiple icosahedral pentamers (assembly 3)
by Noriega, Heather 01 Nov '21

01 Nov '21

Hello, I am trying to make different monomer amounts of the icosahedral for my alphafold prediction. Now, I am able to use 1LP3 as my reference to create a icoshedral pentamer, but that is only 5. I would like to be able to do 10-mer, 15-mer, 20-mer, etc. I however can not seem to connect the pentamers to create the portions of virus capsid. Can you direct me? Thank you, Heather Noriega PhD-Pharmaceutical Science student College of Pharmacy Howard University heather.noriega(a)bison.howard.edu <mailto:heather.noriega@bison.howard.edu> 520-203-1883

mmcif assemblies for alphafold prediction
by Noriega, Heather 30 Oct '21

30 Oct '21

Hello, I am trying to create an asymmetrical assembly similar to 4 and 6 with an alphafold prediction. There are no mmCIF assemblies connected with this prediction, is there a way to add the assemblies, if so how? Or is there another way to create this figure without the assembly? Thank you, Heather Noriega PhD-Pharmaceutical Science student Howard University heather.noriega(a)bison.howard.edu 520-203-1883

Distances in the 3D map - visualisation analysis
by Dmitry Semchonok 29 Oct '21

29 Oct '21

Dear colleagues, I would like to measure the distances of within my 3D map - so I want to draw the arrows from the center of the map to the periphery in different directions and probably depth. (I want to have arrows and an length) Do you have any tips how to do that? Thank you Sincerely, Dmitry
