Re: [chimerax-users] ChimeraX markers to IMOD model

Hi Joe, I made ChimeraX able to read IMOD model files (same as in Chimera), in the current ChimeraX daily build. This does not help with your problem of marking particles for subtomogram averaging. As I added IMOD model reading I looked at whether ChimeraX could write such a file. The file has Fortran binary records and while I could write a file that ChimeraX would read, I am not sure whether IMOD or any other software would read it because the file has lots of information and I don't know what is required and what is optional.

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.

you will probably get a Python traceback which will give some clue as to what is going wrong.

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

Volume series
by Kotaro TANAKA 08 Jun '20

08 Jun '20

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
