opening the session made with the new ChimeraX version using old ChimeraX
by Dmitry Semchonok 31 Jan '24

31 Jan '24

Dear colleagues, I made a session (cxs) in the newest ChimeraX. It contains the models only. How can I open it in the older ChimeraX version? Maybe I can save the session in a different format to be able to open with the older version? Unfortunately, I cannot update the older version on one PC. Thank you. Kind regards, Dmitry

transparency around the model only
by Dmitry Semchonok 31 Jan '24

Dear colleagues, I have a cryo-EM 3D map and model. A model is fitted for only part of my cryo-EM map. Is there a command to make the map transparent only where the model is fitted in? Thank you. Kind regards, Dmitry

Antivirus software warns about "Trojan.Win32.Diple" in 1.7.1 ChimeraX executable
by thomas.coudrat＠gmail.com 31 Jan '24

31 Jan '24

Hi ChimeraX list, When trying to install ChimeraX 1.7.1 Windows (md5: c79878497cfa2c1e0944e732ea4adc21) I get a warning from my antivirus software. See the description here: https://www.virustotal.com/gui/file/cc9b4af4e1a04fc647d082e04f60c111c7aeed1… In case the link doesn't work, it says that "Ikarus" is warning about "Trojan.Win32.Diple", while passing the checks with several other antivirus software. (I've seen a similar thread in the archive but it was from last year, therefore this one might be different) Kind regards, Thomas

Modeller using more than 1 template in Chimera Modeller
by Vladimir Saudek 29 Jan '24

29 Jan '24

Hello, Is it possible to model 3D structure within Chimera using several complementary pdb templates at once? This is possible in the stand alone Modeller but I was unable to find a tutorial/manual instruction how to do it in Chimera. Thank you Vladimir

mixed backbone/sidechain display for N-terminal residue
by hirbond＠utexas.edu 28 Jan '24

28 Jan '24

Hi everyone, I've been working on a protein display that I want to explicitly show the sidechain and backbone atoms of the N terminal residue. The problem is with the cartoon representation. For the N terminal, the cartoon rep goes beyond the CA atom and sticks out. Any tip on how I can change it? I thought of eliminating the pseudobond representation for the CA atom so that the cartoon representation doesn't happen between C and CA but it did not work for me. Thanks!

Hi, I've installed Chimerax 1.7.1 using the .deb. When launching the application from the icon It appears the Chimerax window along with another error panel and after one or two seconds these are closed. If I call Chimerax from a shell I receive the following: $ chimerax NOTE: available bundle cache has not been initialized yet [48347:48390:0126/183239.131894:ERROR:skia_output_surface_impl.cc(927)] surface_size=1224x615 format=6 color_type=4 backend_format.isValid()=0 backend_format.backend()=5 backend_format.asGLFormat()=0 backend_format.asVkFormat()=0 backend_format.asVkFormat() vk_format=0 surface_origin=1 willGlFBO0=0 Segmentation fault (core dumped) If this can be useful on my laptop: $ uname -a Linux xxxx-Lenovo-IdeaPad-S340-15API 5.4.0-74-generic #83-Ubuntu SMP Sat May 8 02:35:39 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux $ glxinfo -B name of display: :0 display: :0 screen: 0 direct rendering: Yes Extended renderer info (GLX_MESA_query_renderer): Vendor: AMD (0x1002) Device: AMD RAVEN (DRM 3.40.0, 5.4.0-74-generic, LLVM 11.0.1) (0x15d8) Version: 20.3.4 Accelerated: yes Video memory: 2048MB Unified memory: no Preferred profile: core (0x1) Max core profile version: 4.6 Max compat profile version: 4.6 Max GLES1 profile version: 1.1 Max GLES[23] profile version: 3.2 Memory info (GL_ATI_meminfo): VBO free memory - total: 866 MB, largest block: 866 MB VBO free aux. memory - total: 5689 MB, largest block: 5689 MB Texture free memory - total: 866 MB, largest block: 866 MB Texture free aux. memory - total: 5689 MB, largest block: 5689 MB Renderbuffer free memory - total: 866 MB, largest block: 866 MB Renderbuffer free aux. memory - total: 5689 MB, largest block: 5689 MB Memory info (GL_NVX_gpu_memory_info): Dedicated video memory: 2048 MB Total available memory: 7928 MB Currently available dedicated video memory: 866 MB OpenGL vendor string: AMD OpenGL renderer string: AMD RAVEN (DRM 3.40.0, 5.4.0-74-generic, LLVM 11.0.1) OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.3.4 OpenGL core profile shading language version string: 4.60 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL version string: 4.6 (Compatibility Profile) Mesa 20.3.4 OpenGL shading language version string: 4.60 OpenGL context flags: (none) OpenGL profile mask: compatibility profile OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.3.4 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 The same problem also with Chimerax 1.7.0 but not 1.6.

CA atoms connected by tether when trying to show sidechains only in a model
by Samuel Haysom 25 Jan '24

25 Jan '24

Hello, I am trying to show only sidechains in one model, so I can compare rotamers with another model where I am displaying cartoon and sidechains. However, when I display sidechains using the sidechain selector (e.g. "show #1 & sidechain") the CA atoms become linked by tethers. [cid:image001.png@01DA4F98.8C977390] How can I suppress this display? I can see its possible to suppress tethers between cartoon helices and a sidechain in the same model but that doesn't seem to apply here as I'm not showing the cartoon at all in the models where the CA tethers are present.

Inquiry on Commercial Licensing for ChimeraX Plugin Development
by Jacky Chen 24 Jan '24

24 Jan '24

Dear Team ChimeraX, My name is Jacky Chen, and I am the sales representative at Oomii. Recently, we initiated a project aimed at developing an innovative ChimeraX plugin, specifically designed to enable interactive augmented reality features. To this end, Oomii has acquired two commercial licenses of ChimeraX in January 2024. As we progress, our intention is to offer the developed bundle for commercial sale to other users. However, upon reviewing the documentation available at: https://www.cgl.ucsf.edu/chimerax/docs/devel/writing_bundles.html, we noticed that it does not specify the licensing particulars for a bundle that utilizes both the ChimeraX API and proprietary code developed by Oomii. We are keen to ensure that our operations align with ChimeraX's licensing policies. Could you please provide guidance on the business rules that apply to the commercial distribution of such plugins? Additionally, if available, could you direct us to any precedent or contact information for companies that have navigated similar pathways? Your assistance in this matter is invaluable to us, and we eagerly await your insights. Thank you very much for your time and support. Warm regards, *Jacky Chen 陳志傑* *Sales Representative* * <https://oomii.com/>* *jackychen(a)oomii.com <jackychen(a)oomii.com>* *2F.-1, No.94, Baozhong Rd.

Feature question: "Worms" plots in "Render By Attribute"
by James Lingford 24 Jan '24

24 Jan '24

Dear ChimeraX team, I was wondering if ChimeraX v1.7+ has the function for rendering attributes by "Worms"? For example, rendering B-factors by the thickness of the backbone. I noticed that it's possible in legacy version of Chimera, which I have since installed and generated worm plots with: https://www.cgl.ucsf.edu/chimera/ImageGallery/framedpecworm.html Is this doable in the latest ChimeraX versions, however? Many thanks for any help you can provide, James -- *James Lingford* | Research Officer, Greening Lab Department of Microbiology, Monash Biomedicine Discovery Institute Monash University Google Scholar <https://scholar.google.com/citations?user=4KSRHTUAAAAJ&hl=en> | Website <https://www.jameslingford.com/>
