Hi, I was able to run chimeraX on ubuntu 21.04 by installing the following package https://answers.launchpad.net/ubuntu/hirsute/amd64/libllvm10/1:10.0.1-6 Then you just need to download chimerax of the following version Ubuntu 20.04 (Linux) 64-bit from their website (deb package). Gabriel

Chimerax for Ubuntu 21.04
by jobiph 16 Aug '21

16 Aug '21

Dear all, is the current version of Chimera for Ubuntu (20.04) compatible with the 21.04 Ubuntu release? If i try to install the 20.04 version a weird dependency error pops up and I can't install the missing library because on the canonical website it states that this library is deprecated. Thank you for your help and kind regards Jonas

All-numeric residue names
by Tristan Croll 16 Aug '21

16 Aug '21

Was just looking at 2rg6, which happens to have a ligand with an all-numeric 3-character ID (287)... clearly not much thinking went into allowing that. Anyway, does the residue selection syntax have a way to disambiguate residue *number* 287 from residue *name* 287?

Coulombic color combined surface
by W. C. 13 Aug '21

13 Aug '21

ChimeraX has no way to color ONE continous surface formed by combining multiple chains with coulombic or hydrophobic. It always color each chain surface separatly . Even though I generated a surface of combined chains by "surface enclose" command, ChimeraX still colors each chian seperately. In Chimera (not ChimearX), I could use surfcat to combine chains, generate one surface for combind chains, and color the surface as one continous. However, that could color large set of molecules. So please make ChimeraX can do the same.

Morphing with ligands
by Volodymyr Dvornyk 10 Aug '21

10 Aug '21

Dear Colleagues, Tried to do morphing of the following structures: 6rdc, 6rep, and 6rd9. All three have the same ligands: ADP, ATP, Mg, and Zn. However, the resulting model lacks all of them. Any thoughts and/or suggestions? Thank you.

Trying to open .py files on Windows gives cPickle error
by Carnes, Jason 09 Aug '21

09 Aug '21

Hello, I am collaborating with someone using ChimeraX on a Mac. Their only option to save modified files results in a .py file extension. When I try to open .py files on my Windows install of ChimeraX I get an error: "ModuleNotFoundError: No module named 'cPickle'" Is there a way to manually install cPickle on my Windows computer that will allow me to open the .py files, or are Mac & PC not compatible?

Difficulties Visualizing Isosurfaces from Cube File - Nathan Wood
by Nathan Wood 09 Aug '21

09 Aug '21

Dear ChimeraX I was having difficulty attempting to visualize computationally generated electrostatic potential isosurfaces originating from a Gaussian *.cube file. I tried to open the cube file from the shell only for it to incompletely visualize. I can provide an image if necessary. I found the following correspondence concerning cube files and isosurfaces, but unfortunately I am unable to resolve the issues of the cube file visualizing. https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2021-April/002126.html <https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2021-April/002126.html> https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2020-May/001110.html <https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2020-May/001110.html> I was curious if anyone has had experience with cubefiles. Any assistance would be greatly appreciated, Very Respectfully, Nathan Wood

Superimpose
by Wisoot Chanit 08 Aug '21

08 Aug '21

Dear ChimeraX team, I am having a quesition. I am going to superimpose 2 monomers of P domain of norovirus GII.3 into a template PDB 6if5, but the template showed that information of its chains are missing. What should I do to make a dimer into 6if5. This is different from PDB 3mfg, which was a templete I used for my previous paper. Thank you. Jay

Re: [chimerax-users] Saving 300dpi high resolution images with ChimeraX
by Elaine Meng 04 Aug '21

04 Aug '21

Hi Nada, ChimeraX questions should be sent to chimerax-users(a)cgl.ucsf.edu (CC'd here so you don't need to do anything this time). ChimeraX does not set the dpi. You just figure out the number of pixels you need and then save in pixels. I.e. if you want 3 inches wide at 600 dpi then you know you need 1800 pixel width, e.g. save myfile.png width 1800 If you open the resulting image file in just about any general image application like Photoshop, Gimp, or Mac Preview (etc.) then you can set the "resolution" or "dpi", but it's really the number of pixels you save in the first place that matters. I hope this helps, Elaine ----- Elaine C.
