When i try to proceed to download icon, the next page displays "cant open page or refresh page, connection failed" I need your assistance in helping me with the download methodology or right website to enable me download the software. Thanks in anticipation for your kindest help. Hello Austine, I don't know what you mean by "proceed to download icon". In the download page, you would click on the link for the installer that you want: <https://www.rbvi.ucsf.edu/chimera/download.html> Then it shows the license, and if you agree, then click the "Accept" button at the bottom of the page to start the download. Occasionally the website is down, but as far as I can tell it is fine right now. I hope this helps, Elaine ----- Elaine C.

Scene transition is delayed in chimera animation
by Shanti Pal Gangwar 10 Mar '21

10 Mar '21

Hi All, I am trying to make scene based animation in chimera where every scene is rotated 360 by using action Roll 360. What I observe is that the scene transitions from 1 scene to another is extremely slow and not continuous also. For some scenes it is fast as well. How can I keep this transition minimum and fixed to all scenes to make a continuous animation. Thank you very much Shanti Pal

Fwd: error code -1073741819

Beni's problem with Chimera not starting was a graphics problem related to supersampling / super-resolution / multisampling. Not clear whether the fix was to change a graphics driver setting or the Chimera multisampling setting. Beni's email below.

Hey there I've been using UCSF chimera for some time with no problems but it is having trouble starting up, this is the error message: *Cannot execute 'gzip': no automatic decompression of .Z filesinitializing general preferencesloading Tixinitializing graphicsReturn code: -1073741819Press return or enter to to exit* precisely like this gentleman: https://plato.cgl.ucsf.edu/pipermail/chimera-users/2019-April/015675.html and this https://www.cgl.ucsf.edu/pipermail/chimera-users/2011-December/007021.html my dxdiag info is attached, nothing wrong jumps to me. What I've tried: - uninstalling and reinstalling Chimera - manually installing GZIP for windows ( https://sourceforge.net/projects/gzip-for-windows/ ) - updating drivers (graphics drivers and chipset drivers) - getting the alpha version of the program - going to and fro compute mode in the the graphical settings I'm using Chimera 1.15 and this is my hardware chipset b550m ryzen 5600x RX 590 in trying to fix it I learned about ChimeraX, I'm learning to use it, but I would still like to keep chimera until i can properly stop and change my workflow thanks so much, let me know if I missed any info

each rotation of the molecule in chimera will unexpectedly add an extra "c" at command line
by xiaoyu liu 03 Mar '21

03 Mar '21

Hello, I'm Xiaoyu Liu, a chimera user. Thank you for developing and sharing this powerful software. I have a problem now and bothered me for a while when using chimera. I'm wondering if you know how to solve it. I downloaded chimera-1.15-mac64.dmg <https://www.cgl.ucsf.edu/chimera/cgi-bin/secure/chimera-get.py?file=mac64/c…> from "https://www.cgl.ucsf.edu/chimera/download.html" for my Mac OS Catalina(10.15.5). When I rotate the molecule with left mouse button, an extra character "c" will be automatically added in command line. Each rotation will result in adding one "c". Here I have some screen shot to show more clearly. [image: image.png] [image: image.png] [image: image.png] I tried to restart my computer. It is helpful within the first 10 minutes after the restart, but later it has the problem again. Please let me know if you know how to solve it. Many thanks! Best, Xiaoyu

problem with pdb file saved from chimera-autodock vina analysis
by Amol Ghodke 03 Mar '21

03 Mar '21

Hi, First of all thank you so much for making such a wonderful tool and sharing it freely with scientific community. I have been using chimera for sometime now and performed docking analysis using autodock vina. I recently come across a problem. After exporting pdb file with desired docking pose, I tried to run protein ligand interaction analysis on PLIP<https://plip-tool.biotec.tu-dresden.de/plip-web/plip/index> server. But ligand in my file does not get recognised for analysis. I opened pdb file in a text editor and upon looking care fully I see chimera saves receptor and ligand as separate model like this ATOM 7453 HD2 PRO A 462 15.986 11.983 20.450 1.00 0.00 H ATOM 7454 HD3 PRO A 462 16.532 10.334 20.885 1.00 0.00 H ENDMDL MODEL 2 HETATM 1 S1 CGT A 1 9.051 5.106 43.099 1.00 0.00 S HETATM 2 C6 CGT A 1 8.150 3.680 42.370 1.00 0.00 C After comparing it with the pdb file from pbd database I removed “ENDMDL” and “MODEL 2” and re-ran the PLIP analysis. This time it works but PLIP also mentions that – [cid:image001.png@01D7103D.5D0AB030] Analysis went well but the .pse file that I get from PLIP server does not allow me to show ligand in stick format in Pymol software. I suspect this is due to the original pdb file format. I also noticed that pdb file when opened in pymol shows ligand and receptor as different states which is not correct (if I am right). I have attached both original pdb file that I saved from Chimera-autodock vina and pse file from PLIP analysis. May I request to help me resolve this issue? Please let me know if you need any further information or clarification.

Dear all, I want to fit a pdb structure into a cryoem map. Accordingly to the youtube tutorials I open both, place the correct pixel size, centre, and then I want to zoom only on the pdb file, but inactivating the cryoem map doesn't work: both maps zoom together. What am I doing wrong?

editing session file
by Olivier Bignucolo 02 Mar '21

02 Mar '21

Dear Chimera-users, I am new to Chimera. I saved a session.py file that manages the appearance of, say, folder1/proteinA.pdb. I would like to apply exactly the same formats, colors, etc... to proteinB.pdb located in folder2. I edited session.py but was unable to find out how to do it. It seems that the python script does not contain any line like: "open("filename","r") or anything similar. How can I reuse session.py for a new pdb file? Thanks Olivier
