ChimeraX not starting up using win10
by Bernd M. Schmidt 05 May '21

05 May '21

Dear ChimeraX users and coders, Thanks for the hard work and for providing the community with such great program. I cannot run Chimera on my desktop PC. After clicking in win10, the cursor indicates something is happening for three seconds, then nothing happens and also no error message or anything appeares Before that, I ran Chimera 1.14rc successfully, since installation of ChimeraX and also with ChimeraX 1.2, this happens. I deinstalled everything and installed first the latest python release (3.9.5), then ChimeraX 1.2. But no change, nothing. Reading the newsgroup suggested running debug mode, finally giving some error message, as seen below. C:\Program Files\ChimeraX 1.2\bin\lib\site-packages\win32\lib\pywintypes.py:2: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses import imp, sys, os Windows fatal exception: access violation Current thread 0x000023f8 (most recent call first): File "C:\Program Files\ChimeraX 1.2\bin\lib\site-packages\chimerax\ui\gui.py", line 157 in __init__ File "C:\Program Files\ChimeraX 1.2\bin\lib\site-packages\ChimeraX_main.py", line 577 in init File "C:\Program Files\ChimeraX 1.2\bin\lib\site-packages\ChimeraX_main.py", line 1015 in <module> File "C:\Program Files\ChimeraX 1.2\bin\lib\runpy.py", line 87 in _run_code File "C:\Program Files\ChimeraX 1.2\bin\lib\runpy.py", line 194 in _run_module_as_main C:\Program Files\ChimeraX 1.2\bin> Happy for some help. Many greetings bernd

Saving name attribute
by David Leeming 04 May '21

04 May '21

Hi, I'm attempting to use a python script to save the names of each residue in a protein The code I have is as follows: import chimerax, sys from chimerax.core.commands import run cwd = (str(sys.argv[0][:-17])) prot = "/A" run(session, "open 3GDM") run(session, "save " + str(cwd) + "/script_content/sasa/name.defattr " + str(prot) + " & protein attrName r:name format defattr") The command being input into the command line of ChimeraX by the script is as follows: "save [file path]/name.defattr /A & protein attrName r:name format defattr" I've also tried using: "save [file path]/name.defattr attrName r:name format defattr models /A & protein" However, both commands give me a file with all the residues and all the names contained within the model rather than just the chain I'm interested in. Could you advise on how I can better use this command to save a file with the residue positions and corresponding amino acid for each residue from a single chain only? I've attached the resultant file to this email. Kind regards, David

assigning 3.10 helices to a pdb
by Sheena Vasquez 03 May '21

03 May '21

Hi everyone, I was wondering if there's a way to reassign alpha-helices to 3.10 helices in chimeraX? I've been using the setattr /A:###-### res ss_type 1 command, but it seems as if there's only the option to assign alpha helices (ss_type 1). If I try ss_type 5 (5 is the assigned number for 3.10 helices in the pdb), the helix is lost. Any help with this is greatly appreciated! Take care, Sheena

ChimeraX Cheat Sheet/List
by André Graça 30 Apr '21

30 Apr '21

Hi everyone, There is no doubt that we have a very good documentation on the different functions of ChimeraX as well as for Chimera. Nevertheless, sometimes it is easy to have a summarized sheet with the most used functions and options. I plan to start doing a cheat sheet for me, and it would be great to make it open source. However I might not be aware of the existence of one already. Does anyone know/have one and would be willing to share with the community, or point me to one available online? Or has the ChimeraX team any plans to do one in the near future? Thank you, André

Hello Tom, Hope you are doing well. I am creating a GUI, and I have some problems. At the right bottom DL Struct window, I want to click the browse button and select a file, but it holds this error. I wonder if you know what's the problem? (My goal is let users find or input the path of a file, and use this path to submit jobs) Best regards, Yongcheng [image: Screen Shot 2021-04-29 at 1.24.02 PM.png] On Fri, Apr 23, 2021 at 7:20 PM Yongcheng MU <ymu004(a)odu.edu> wrote: > Hello Tom, > > Thank you for the information.

Display chain annotations w/o having to reopen files
by Alexander Julian 28 Apr '21

28 Apr '21

Good afternoon, I was wondering if there was any built-in functionality to show the chain annotations that are shown when the file is first open? When I save a session (.cxs) and reopen it later, this information is missing. Best, Alexander -- *Alexander T.

Hide dashed lines (chain breaks)
by Gabriele Cerutti 28 Apr '21

Hello, I am displaying a protein molecule in cartoon representation and chimeraX automatically shows dashed lines for chain breaks (see attached). Is there a way to hide these dashed lines? Best, Gabriele [image: Screen Shot 2021-04-28 at 9.50.54 AM.png]

Adding amino acids to end of chain
by Tom Goddard 26 Apr '21

26 Apr '21

Alexis Rohou asked on Twitter In @UCSFChimeraX <https://twitter.com/UCSFChimeraX> 1.1.1 and #Isolde <https://twitter.com/hashtag/Isolde?src=hashtag_click> by @CrollTristan <https://twitter.com/CrollTristan> is there an easy way to add aa residues to the end of a chain? https://twitter.com/AlexisRohou/status/1386171500604977152 <https://twitter.com/AlexisRohou/status/1386171500604977152> Elaine says: There isn't an "add amino acid" yet in ChimeraX, only Chimera.... unless ISOLDE can do it (I don't know). So maybe it's an ISOLDE question. ChimeraX itself has building peptides from scratch but not sticking them on to the end of an existing peptide. Build Structure, Start Structure: peptide <https://rbvi.ucsf.edu/chimerax/docs/user/tools/buildstructure.html#start <https://rbvi.ucsf.edu/chimerax/docs/user/tools/buildstructure.html#start>> or command "build start peptide" <https://rbvi.ucsf.edu/chimerax/docs/user/commands/build.html#start <https://rbvi.ucsf.edu/chimerax/docs/user/commands/build.html#start>> Elaine
