Place Objects output to mrc
by Ricardo Righetto 20 May '22

20 May '22

Hi, Regarding https://www.rbvi.ucsf.edu/pipermail/chimera-users/2022-March/018516.html I stumbled upon this thread somewhat late, so here is my approach to do what Pranav asked, just in case: 1. Use the "Place Objects" plugin to map back your particles into the tomogram, using STL files to represent the average 2. Generate an MRC volume made up entirely of "ones", exactly the same size as your tomogram. For example, for a volume that is 928x928x464 voxels one can do this in EMAN using: $ e2proc3d.py :928:928:464:1 ones_bin4.mrc You could obviously use some other program to do the same thing, or Python, MATLAB, etc. 3. Load this "ones" volume in your Chimera session. Make sure all regions are loaded in step 1, e.g. vol #2 style surface step 1 level 0.5 region all (the volume doesn't have to be visible, though) 4. Mask your "ones" volume using the surface of the mapbacks from "Place Object", e.g.: mask #1 #2 fullmap true 5. Save the new, masked volume as an MRC file The result is essentially a binary volume (well, not exactly because of the masking interpolation) where voxels of your mapped-back particles are 1 and the rest is 0. This is quite useful to compose segmentations and mapbacks on tomograms in Chimera or ChimeraX having full control like we do with any MRC volume (unlike e.g. STL or COLLADA objects). Note you may get some artifacts on the edges, so you might have to play a bit with the thresholds both when creating the STL of your subtomogram average and when displaying your new volume "sculpted" by the mapbacks, to minimize those. The results however have been good enough in my experience, working with low-resolution averages :-) Hope this helps! Best wishes, -- Ricardo Diogo Righetto

Allocating GPUs
by Giono Matteo (PSI) 19 May '22

19 May '22

Dear all, Does anyone know if it’s possible to make Chimera use GPUs instead of CPUs? I have a 2021 Macbook Pro with 12-core GPUs and knowing that all the work is done by the CPU make all these GPUs kind of useless. Best, MG

USCF CTRL + Left Click
by Luke Kurfman-Student 19 May '22

19 May '22

Hello Sr./Ms., Most everyone in my laboratory has access to UCSF Chimera and can use it with no issues. However, one new person has had trouble selecting atoms. Specifically, neither CTRL + Left Click nor CTRL + SHIFT + Left Click appear to work on selecting atoms in a molecular geometry, even though their computer can run the program. They can translate, rotate, and zoom in-and-out of the geometry, and they can use actions such as "Select All" . However, they cannot deselect individual atoms once the entire geometry is selected, and they can only CTRL + Left Click outside the geometry to deselect the entire geometry. Additionally, drag-clicking does not appear to work. CTRL + Click is a fundamental feature that our group uses, especially since we use Chimera for journal figures. Are there any suggestions on how to troubleshoot the issue with selecting atoms? For reference, their computer runs Windows 10 and operates on a x64 bit system. Any help is appreciated, Luke

Set scale factors from displayed contours?
by Oliver Clarke 17 May '22

17 May '22

Hi, When combining maps using vop maximum (or volume maximum in chimerax), we often want to adjust the scale factors of the maps such that the overlapping bits of two aligned maps are visually on the same scale. It is possible to calculate the appropriate scale factors from the displayed thresholds, but this becomes a little time consuming when combining many maps. Would it be possible to add a flag, something like "get scalefactor from display thresholds" that would take care of this automatically? Cheers Oli

Assigning nucleotide representation to non-canonical nucleotides
by Jérôme Rihon 17 May '22

17 May '22

Dear I was wondering if there is a way to represent non-canonical (otherwise known as xenobiotic) nucleic acids through UCSF Chimera (specifically, not ChimeraX .. haven't made the jump yet). I've looked through your documentation on the `nucleotides` section but was not able to find something along those lines. My PI told me it was possible, but I can't seem to find it. My apologies if I should be looking for this function elsewhere, but I thought it'd be easier to just ask. Many thanks in advance! Kind regards, Met vriendelijke groeten, Cordialement, ______________________ Rihon Jérôme jerome.rihon(a)kuleuven.be | +32 16 32 53 57 PhD researcher @Rega Institute for Medical Research | Laboratory of Medicinal Chemistry | Computational Research Herestraat 49 - box 1041, 3000 Leuven

Making a movie from map series while keeping map's colors
by Michal Arie Shmuelov 16 May '22

16 May '22

Hi everyone, I have 20 maps (from 3D variability analysis) that I open as series in chimeraX. I'm coloring the map series using the command "color zone #X near #X distance X" (coloring the map according to pdb model). Next I'm trying to make a movie of this map series while retaining the map colors. For some reason when the morph/ vseries starts to run the colors disappear. Can someone help me to solve this problem? What are the commands that I should write? Thanks, Michal

Can't open web file
by Emma Belcher 13 May '22

13 May '22

Hi there, I am a complete beginner with Chimera so apologies for the very basic question. I am trying to open a Consurf output which is a .chimerax file. I have downloaded Chimera to do this and have not changed any default settings (running MacOS Monterey 12.2.1). When I try to open the file (either by clicking “Open with Chimera” on the file or opening Chimera and going File > Open… and selecting the file), it comes up with the following error message: Error reading consurf_1652376787.chimerax: Couldn't find url 'https://consurf.tau.ac.il/results/1652376787/msa_file_fasta.aln.clustalw': [Errno socket error] [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661) I have no idea what this means or how to fix it, so would appreciate any tips! Thank you, Emma Belcher

Save reply log through chimera command line
by Reeki Emrizal 13 May '22

13 May '22

Hi I working on an automated python script to calculate the rmsd between two molecules using rmsd command. I'm using --nogui when running the script. The standard output did not show the rmsd value. When using the chimera gui, I noticed that the rmsd value is shown in the reply log. Is there a way I could save the content of the reply log through python script? I found previous post with similar issue that use: from chimera.tkgui import saveReplyLog saveReplyLog(path) The solution does not work for me though as the text file is empty even though there is content in the reply log. Kind Regards
