ChimeraX markers to IMOD model
by Atherton, Joseph 16 Jun '20

16 Jun '20

Hi, I'd like to use the markers function in ChimeraX to make an IMOD 'model' for use in PEET for subtomogram averaging. ChimeraX's 'planes' function makes it a convenient program for doing this. Is such an export/conversion possible?

Re: [chimerax-users] ChimeraX does not start after installation

Hi Józef, OpenGL provides no mechanism for an applications to choose among multiple GPUs, or even know that multiple GPUs are available. It is up to your operating system to choose the GPU.

This is weird because I have recently updated to the latest NVidia drivers, which should have fixed this (and it didn't). I have been searching around based on your pointers and I suspect that Windows somehow tells ChimeraX to use the integrated graphics rather than one of the four NVidia GPUs (I guess Intel graphics is the GPU default in the Win installation) I have never checked or tried to update the driver for the integrated graphics so it might be that it is using some ancient generic driver (I just assumed that Windows would automatically directed ChimeraX to the more powerful GPU options). > I have found some instructions to force ChimeraX to use NVidia GPUs so I will try this (when I can access my workstation again). > > Best, > Józef > From: Tom Goddard <goddard(a)sonic.net> > Sent: Monday, June 15, 2020 5:46 PM > To: Lewandowski, Jozef <J.R.Lewandowski(a)warwick.ac.uk> > Cc: ChimeraX Users Help <chimerax-users(a)cgl.ucsf.edu> > Subject: Re: [chimerax-users] ChimeraX does not start after installation > > Hi Józef, > > The reason ChimeraX does not start on hour Windows computer is given in the middle of this error message: > > ERROR: ChimeraX requires OpenGL graphics version 3.3. > Your computer graphics driver provided version 1.1 > > Your OpenGL graphics driver is not working.

Hi Józef, The reason ChimeraX does not start on hour Windows computer is given in the middle of this error message: ERROR: ChimeraX requires OpenGL graphics version 3.3. Your computer graphics driver provided version 1.1 Your OpenGL graphics driver is not working. Version 1.1 is from the 1990s and is what Windows gives you when you have no working graphics driver. So the fix will be to install a working graphics driver. When ChimeraX does not get a usable graphics driver it is supposed to still start and present a message explaining this. I am not sure why it crashed in your case. But I see in your error message Windows fatal exception: code 0x80000003 and searching online this says you have misconfigured Windows system files. All the top hits when searching for that error look like scams telling you how to use their special utility to "fix" your system. Be cautious -- I would not suggest running any spacial "cleaner" tools as they are usually malware.

Hello, I am using the new ChimeraX, and it is great thus far! One issue I have come across is that if I want to display sidechains that are directly adjacent a connective line links the alpha carbons that I can't seem to get rid of. Tried lots of little workarounds, but can't seem to get it to go away (see attached picture). Is this just a bug I will have to deal with or is there a workaround?

Cupy dependency for ChimeraX bundle
by Arthur Ecoffet 09 Jun '20

09 Jun '20

Hi, I am currently trying to develop a bundle for ChimeraX and the methods implemented can both run on GPU (using Cupy with a Cuda dependency) or on CPU. I am wondering how to deal with this "pseudo-dependency" with cupy, since it is not necessary to run the code but it is more computationally efficient. If a Cupy dependency is written in the "bundle_info.xml" file, will it create errors for computers without Nvidia Cuda installed ? Is there any way for users to install supplemental package by hand directly in chimeraX python as it was possible with Chimera ? Or is the only solution to add by hand a dependency line in the xml file ? Thanks, Arthur

Hi, I'm trying to create a morphing movie of a series of 3D maps. For that purpose, if I understand correctly, I need a volume series (vseries) of those maps, and according to the documentation (https://www.rbvi.ucsf.edu/chimerax/docs/user/trajectories.html#vseries) I should obtain a volume series simply by opening the maps at once in a file opening dialogue. I attached a screen shot of the Models panel after opening my maps, and my question is, are those maps already consisting a volume series? vseries commands fail with 'No volume series specified' I would appreciate your comments, thank you Best regards, Kotaro

mesh grid sampling
by Steve Chou 08 Jun '20

08 Jun '20

Dear ChimeraX developers and users, I'm trying to display a map as mesh in ChimeraX, but the grid sampling is too sparse. *volume #1 style mesh level 0.02 step 1 color blue* Is there a way to increase the grid sampling, so that the chicken wires look denser? Thanks in advance! Steve -- Steve Chou

2D and 3D objects
by Jazzar, Rodolphe 04 Jun '20

04 Jun '20

Hi, First of all, this is a great program, and I am barely using it to full extent of its possibilities. I am currently interested in combining a 3D object (a molecule.pdb) and a 2D object/plane/image (as a .png or any other). The idea being that I want to show a slice of an ELF plot, with the 3D molecule embedded through the 2D plot. Good news is that I can import both objects (.pdb and .png). However I face a size issue with the 2D object, which is considerably bigger than the 3D one. Would you know if I can size down a 2D object, or enlarge a 3D one respectively. All in all would you know if chimeraX can generate something like the picture attached by combining a 2D and a 3D object. Thanks for your time, Cheers, Rodolphe [cid:D31DAF51-91B8-4F78-94B3-4C0FCD9C860E] Dr. Rodolphe Jazzar, CNRS Research Associate - (French National Centre for Scientific Research) UCSD-UMI 3555 ORCID : 0000-0002-4156-7826 Office: (858)-534-5315 Mobile: 858-337-2228 University of California, San Diego, 5213 Pacific Hall, Department of Chemistry, 9500 Gilman Dr, # 0343, La Jolla, CA 92093-0343 http://bertrandgroup.ucsd.edu<http://bertrandgroup.ucsd.edu/> https://northamerica.cnrs.fr<https://northamerica.cnrs.fr/> http://www.cnrs.fr/en/cnrs [cid:image001.png@01CFDE12.00855770]

Re: [chimerax-users] ChimeraX cross links

As I understand it there are two ways for atomic structures with crosslinks to be shown in ChimeraX: (1) some integrative modeling structures include such crosslinks. If you download the "cif" from the PDB IHM site <https://pdb-dev.wwpdb.org/> and then change its filename suffix to "ihm" instead, then you can open it in ChimeraX. If the IHM model has crosslinks, they should show up somewhere in the model hierarchy of that data, which you can explore in the Models panel. An example of one with crosslinks is the BBSome: <https://pdb-dev.wwpdb.org/entry.html?PDBDEV_00000018> (2) or if you just have any atomic structure already in ChimeraX and you want to add crosslinks, you can read in pseudobond file (filename.pb), which is just a series of atom-pair specifications in plain text. You can also include color, radius, number of dashes. The file description is the bottom section of this page: <http://rbvi.ucsf.edu/chimerax/docs/user/pseudobonds.html> Also, you can change colors, number of dashes, and radius of any pseudobonds already in the structure or previously added, just using the commands "color" "style" and "size"; see the links in the top section of the pseudobonds page. There is a chimerax mailing list CC-d here for questions (unless they contain private data). I hope this helps, Elaine ----- Elaine C.

Installation of ChimeraX in Centos 7
by Gaya Yadav 01 Jun '20

01 Jun '20

?Dear Sir/Madam, I am trying to install Chimera X in the Centos 7 in my local directory. I installed it by converting it chimerax-rc.cpio?. But I cannot launch it, it was showing error about the openGL. Is that because of the openGL or it is not installed properly? Here is the error: WARNING: QXcbConnection: XCB error: 145 (Unknown), sequence: 178, resource id: 0, major code: 139 (Unknown), minor code: 20 NOTE: available bundle cache has not been initialized yet ERROR: ChimeraX requires OpenGL graphics version 3.3.

Re: [chimerax-users] 3D stereo lighting is not the same as mono
by Tom Goddard 27 May '20

Try "camera sbs" and see if shadows look right. If they do look ok, but stereo does not then it will require some debugging with a stereo system that reproduces the problem and I am not able to test that until quarantine is over.

For me other two eye modes like VR and SBS (side-by-side) have correct shadows. The problem may be a graphics driver bug effecting shadow calculation.

Recreating views
by Martin Montgomery 22 May '20

22 May '20

Hi, I have a session file that contains everything I need to make figures for a paper. With pymol, I saved the get_view matrix in a text file for each view which meant that with one session file I could easily recreate the views if I needed to go back and tweak a figure. In ChimeraX, the closest way that I found to replicate this was to use named views. Am happy to supply a session file if it helps also happy to be educated if there is a better way of doing this, especially as now the ChimeraX session files can get rather large.

Save/restore scene?
by Oliver Clarke 20 May '20

20 May '20

Hi ChimeraX-ers, Is there currently an equivalent of the "scene" command from Chimera? It was super helpful to be able to quickly switch between different (and often complex) representations of a molecule. I know the view command for saving and restoring orientations, and the "name" command for saving selections, but I can't find an equivalent of scene. I'm guessing it's not yet implemented, but count me as one vote for porting it over after 1.0 is out the door, it was super helpful in Chimera! Cheers Oli

Feature suggestion - show color code in picker?
by Oliver Clarke 19 May '20

19 May '20

Hi, I love the color editor in ChimeraX, it is much nicer than the one in Chimera and is super useful! One minor suggestion - would it be possible to add a dynamically updated label showing in the editor the current color code? This sometimes shows up in the log but not always, and it is useful to have easily copy-able for use in scripts and aliases. Cheers Oli

Focus in ChimeraX
by Luca Pellegrini 18 May '20

Hi, What is the ChimeraX equivalent to the Focus command in Chimera? I have selected a portion of a structure, and would like to bring it into focus without dragging it into view. Also Focus would automatically set the selection as the pivot point. Best wishes, Luca Luca Pellegrini, PhD Department of Biochemistry University of Cambridge Cambridge CB2 1GA lp212(a)cam.ac.uk

Turntable rotation

I would like to create an animation where the camera is spun around at a constant azimuthal angle so the object appears to spin on a tabletop. Currently, when I use roll, when it spins to the backside I see underneath the model rather than remaining on top. Any help is greatly appreciated. -Brandon ____________________ Brandon Scott, PhD CZI Imaging Scientist, Research Assistant Professor SDSMT, Nanoscience and Nanoengineering

ChimeraX accepts files dragged and dropped on the application. On macOS (and probably Linux and Windows) I should be able to run a shell command that says drop this file on ChimeraX.

Stereo and VR support
by Gökhan Tolun 13 May '20

13 May '20

Hi, Would it be possible to make the graphics window undockable, too, Like the other ones? This would allow the use of stereo monitors with SBS and tb support, which does not work currently with menus, etc. surrounding the graphics window. Also, will you implement DTI stereo as in Chimera? By the way, if theres a way of making ISOLDE work in VR, thatd be great! Thanks, Gökhan
