Mask Question in windows Chimera
by Zhang, Ruojing 04 Jul '22

04 Jul '22

To whom it may concern, Hello, this may sound like a silly question. May I ask how to use Mask in Volume? For some unknown reasons, I could not find the Mask button in Volume Viewer and neither in the tool taskbar. The input files are pdb and mrc file. I used Fit in Map to align structure and map. Then I selected the whole structure. When I went back to mask the map, I could not find the Mask button in Volume Viewer. When I tried to run in the command line (mask), it shows "missing required arguments: Volume, SurfaceSpec". Could you please help? Thank you Jing

ChimeraX Version 1.4 on CentOS/RHEL 7
by Long Gui 01 Jul '22

01 Jul '22

Dear Chimera community, We are interested in the new version of the ChimeraX/1.4 but we could not find the installation file of ChimeraX/1.4 on our CentOS/RHEL 7 system. Only ChimeraX/1.3 supports CentOS/RHEL 7. So we would like to ask if there is a way to install ChimeraX/1.4 on our CentOS/RHEL 7 system? In addition, our computational source would prefer to install the program using docker. Currently I only find this docker file supports ChimeraX/1.3 https://github.com/maduprey/chimerax-docker/ ? Have anyone tried it for ChimeraX/1.4 yet? Thanks!

AutoDock Vina error on Chimera
by Utkarsh Narsaria 30 Jun '22

30 Jun '22

Dear Team, I am using chimera for a typical protein-ligand docking study. The ligands were prepared in chimera itself using the dockprep options using gasteiger charges and amber ff14SB force field. While docking the same using AutoDock Vina function in Chimera , we encountered few errors for some of the ligands. The errors are explained as follows : 1. "" Ho" is not a valid dock type AutoDock atom types are case-sensitive." 2. Autodock Vina Error on Chimera: "ValueError: Could not find an atomic number for Hc Hc" Any inputs regarding these will be helpful in resolving the issues. Regards, Utkarsh

How to show hydrophobic interactions
by Kenji MATSUI 17 Jun '22

17 Jun '22

Dear Chimera Thank you for taking the time to answer my question the other day. I also apologize for contacting you outside of business hours due to the time difference. I'm Kenji Matsui, a second-year master's student at a national university in Japan. I have shown hydrophobic interactions between ligands and amino acid residues, how should I display them? I refer to these methods. But, I did not know where to find Examine residues. Therefore, could you please tell me the location of Examine residues? If possible, we would appreciate it if you could attach a diagram after the operation so that we can confirm the operating procedure. *A:Find hydrophobic interactions* Select >> Residue(s) (either in entire structure or within a selected set (see above $ or %)) >> Amino acid category >> hydrophobic >> Action >> Atoms/Bonds >> Show >> Examine residues >> Mouse over atoms or Left click on them to identify them --------------------------------------------------------------------------- 松井健治東京農工大学大学院工学府産業技術専攻修士 2年〒184-8588 東京都小金井市中町2-24-16 Kenji Matsui Graduate School of Tokyo University of Agriculture and Technology M2 2-24-16, Nakamachi, Koganei-shi, Tokyo 184-8588, Japan Mail: s214903z(a)st.go.tuat.ac.jp

Discrepancies Between Running Python Script From Terminal and GUI
by Rafi Brent 06 Jun '22

06 Jun '22

To whom it may concern, I have a set of about 20,000 pdb files to which I would like to add Hydrogens, add partial charges, and convert to the mol2 format. I have written a python script to perform these tasks, which it does without issue when opened from the GUI using the "open" option in the top left corner. However, as soon as the script start srunning, I become unable to interact with the Chimera GUI and my computer warns that the application is not responding. While it continues to iterate through the pdb files and convert them to mol2 files, this process slows down drastically over time, from one file per second to over 30 seconds between files, a rate that is prohibitively slow. It is not clear to me why these issues are occurring, as there is nothing about the way my script is written that should increase the computational load over time. Based on the unresponsiveness of the Chimera application, I assumed that the slowdown might have something to do with the GUI, so I instead ran my script from the terminal, using chimera -- nogui python_script.py . This resulted in a rate of file conversion that was much faster than the GUI even before its slowdown, but it raised an error that was never a problem in the GUI: Cannot properly run "/Applications/Chimera.app/Contents/Resources/bin/amber18/bin/sqm -O -i sqm.in -o sqm.out". This only occurred on nonstandard amino acid residues, but the error was not solely determined by the residue's identity, as many carboxylated lysine residues were processed properly before the system encountered one particular file whose KCX residue caused it to crash. However, the error is consistent, meaning that the same KCX residue on that particular file always causes the program to crash. I have had no luck searching for the error online, but I am happy to include the entire error message in context if that would be helpful. More generally, I don't understand why running the exact same python script through the GUI and through the terminal window gives such different results. I'm happy to do it either way as long as the operation can be completed successfully within a day or two, and I would be very thankful for any advice you may have. Sincerely, Rafi Brent

Dear Chimera Thank you for your support the other day. I also apologize for contacting you outside of business hours due to the time difference. Excuse me, I have a question about the issue of ligand topology for the docking study. ligand: 25-hydroxy cholesterol The topology did not match when I used this ligand for the docking study. Could you tell me how to solve this problem? The thing I tried 1. I tried to add hydrogen atoms on UCSF Chimera by following the URL below, but it did not work Reference: https://www.swissparam.ch/SwissParam_gromacs_tutorial.html 2. I tried to change the conformation of the C23-24 part, but the situation won't be changed.

HBONDS comparing GROMACS and CHIMERA
by Sourpis, Anastasios 25 May '22

25 May '22

Dear All, I would like to ask about the hydrogen bonds' built-in configuration of CHIMERA. Can I possibly have some insight into how it works? Regarding the distance and angle constraints do you have any graphical representation of the conditions. I would like to attach a figure and ask if this is the correct applying configuration regarding the distance and the angle (hbonds_lst.pdf). Also, I would like to share with you the output when I compare gmx hbond using GROMACS and chimera. ATTENTION: using gmx hbond I have the connected atoms via hydrogen, but the two configurations are essentially different (chimera_(molecules).tga and gromacs_atomonly.tga). Thank you in advance. Kind regards, Tasos Sourpis

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

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

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!

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 12 May '22

12 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
