display bond lengths and angles
by Thomas Evangelidis 17 May '19

17 May '19

Hello, Is it possible to load a small molecule in Chimera and display all bond lengths and angle values, pretty much as you can do using labelopt option for the atom names? If not directly, could you please give me some hints about how to write a Python script to do it? I thank you in advance for your help.

Still won't work after libfreetype.so* and libz.so* removal
by Яцкевич Максим 14 May '19

14 May '19

Hi! I am running Fedora 29. Now I'm trying to install chimera-1.13.1-linux_x86_64.bin. After successful installation it failed to create a window in a desktop applecation menu. So I followed the instructions on the web-site (http://www.cgl.ucsf.edu/chimera/data/downloads/1.13.1/linux_x86_64.html) After running the command <dir_name>/bin/xdg-setup install it stumbled upon the same error that was discussed in this thread (https://www.cgl.ucsf.edu/pipermail/chimera-users/2018-November/015237.html) Traceback (most recent call last): File "/home/sec/.local/chimera/share/__main__.py", line 73, in <module> value = chimeraInit.init(sys.argv) File "/home/sec/.local/chimera/share/chimeraInit.py", line 666, in init import chimera File "/home/sec/.local/chimera/share/chimera/__init__.py", line 2777, in <module> from SimpleSession import BEGIN_RESTORE_SESSION, END_RESTORE_SESSION File "/home/sec/.local/chimera/share/SimpleSession/__init__.py", line 14, in <module> from save import saveSession, sessionID, noAutoRestore, autoRestorable, \ File "/home/sec/.local/chimera/share/SimpleSession/save.py", line 13, in <module> from chimera import replyobj, selection, SessionPDBio, version File "/home/sec/.local/chimera/share/chimera/replyobj.py", line 24, in <module> import Tkinter File "/home/sec/.local/chimera/lib/python2.7/lib-tk/Tkinter.py", line 39, in <module> import _tkinter # If this fails your Python may not be configured for Tk ImportError: /usr/lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var So I followed your advise and removed the corresponding files: > rm ~/.local/chimera/lib/libz.so* > rm ~/.local/chimera/lib/libfreetype.so* Unfortunately it didn't solve the problem. So after typing: > ~/.local/chimera/bin/xdg-setup install It complained that it cannot find the libz.so file!

Upload color scheme
by Cornelius Hunter 10 May '19

10 May '19

I am looking for a 3D protein viewer that allows me to visualize the protein tertiary structure using my own color assignments, for each residue (or alpha carbon). In other words I would upload a file, with a value for each residue, which would drive the color assignments. Thx

Re: [Chimera-users] Non-standard atom names

Hi Eric So I have been only using dock6 for docking and now want to venture in using dock3. I tried checking online for tutorials that I could look at but there are just a couple of them. On the UCSF website, there is a tutorial but requires the use of dock blaster. I just have a few questions; Is there another way of using dock3.6 without using dock blaster? Is there another simpler tutorial for dock3.6 that you could recommend me to use? Are the dock 3.6 steps similar to the steps of dock6?

I recommend using the Dock Prep tool (Tools→Structure Editing→Dock Prep), which will use a rotamer library to fill out missing/incomplete side chains before adding hydrogens and assigning charges. Use the dialog check boxes to turn off any Dock Prep steps you don’t want (e.g. Write Mol2 file). Applying a lot of rotamers takes a few minutes, so you might want to bring up the Reply Log first (Favorites→Reply Log) so you can keep an eye on the Dock Prep progress while you possibly do something else. > > ―Eric > > Eric Pettersen > UCSF Computer Graphics Lab > >> On Apr 11, 2019, at 8:26 PM, Sid Majaha <sidumomajaha(a)live.com <mailto:sidumomajaha@live.com>> wrote: >> >> >> Hi Eric >> >> Problems with atom names in adding charge to a receptor using Chimera v1.13.1 >> (ToolsàSurface Binding/AnalysisàAdd charge) >> I first added my H to prepare my receptor.

RR distance map, scale normalization
by Arvind SHARMA 07 May '19

07 May '19

Hi, I am comparing four drug bound structures of homologous proteins to their unbound structures in chimera RR distance maps. These structures vary to different degree to unbound structures and I want to show that in four individual RR distance maps (each bound structure to unbound structure). The problem is that the scale varies each time and I was wondering if there is a way to normalize the scale? or set the color code so that, for e.g, for stdv of 10 its red in all cases and below 5 its always white. Thanks. Best wishes, Arvind.

Handling electrostatic potential in cube format
by Boaz Shaanan 06 May '19

06 May '19

Hi, It seems as if the new Delphi version (v8.4) only knows to produce potential phi files in cube format. Oh well. I'm beginning to play with this format via the volume viewer but so far the fit of the surface to the atomic model is bad, let alone that potential values on the surface (as reported by moving the mouse on the surface) make no sense. I'm wondering whether there is a chance to achieve as nice a fit of the cube surface to the protein model as is easily achieved with the good old .phi format and surface command. So far I'm lost. I'd appreciate any clues. Luckily, I still keep the older version but there might be some improvements in the potential calculations in the newer version. Thanks for your help.

Re: [Chimera-users] [chimera-dev] Loop refinement in chain A and Chain B
by Elaine Meng 06 May '19

06 May '19

Hi Aashish, The address for questions about using Chimera is chimera-users(a)cgl.ucsf.edu (CC’d here). Chimera-dev is for programming questions. It sounds like you did find the “model/refine loops” dialog for using the Modeller web service. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/m…> <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/m…> In that dialog, you would need to choose either “non-terminal missing structure” (if the missing residues are in the middle) or “all missing structure” (if some of the missing residues are in the termini), and also enter a license key for running Modeller. However, I have no idea what you mean by “not running,” so I can’t give any more help than that. Also, be aware that in Chimera using this dialog, you can only model one chain at a time. I.e. when it is adding the residues to chain A it does not care if they are in a bad place relative to chain B, and vice versa. Our newer program ChimeraX has the advantage that you can sensibly model the dimer using the Modeller web service, with the two chains “seeing” each other. However, to use that you would have to download and learn a different program. <http://www.rbvi.ucsf.edu/chimerax/index.html> <http://www.rbvi.ucsf.edu/chimerax/download.html> <http://www.rbvi.ucsf.edu/chimerax/docs/user/tools/modeller.html#comparative> I hope this helps, Elaine ----- Elaine C.

Good day! I am currently using UCSF Chimera for my protein structure analysis. However, I cannot find the active site of my protein structure. How do I find the active site, including the amino acids in it using UCSF Chimera? Thank you. Regards, Abryn

Hi Again, Following my complaint on the cube format I started to play with .dx format of APBS which so far seems more promising in how it projects on the protein surface.

You can?t do it in nogui mode since the MAV window has the alignment data. You would be able to do it in nogui mode in ChimeraX, but the code would be significantly different of course. Anyway, if you are doing this in a loop you may want to call mav.Quit() after saving your alignment in order to quit MAV and conserve memory. ?Eric Eric Pettersen UCSF Computer Graphics Lab > On May 3, 2019, at 2:03 PM, Hernando J Sosa <hernando.sosa(a)einstein.yu.edu> wrote: > > Dear Chimera, > > Is there a command option to save a sequence alignment (after executing matchmaker) or a way to do it in a python script? > > Thanks > > H. > > > > > > _______________________________________________ > Chimera-users mailing list: Chimera-users(a)cgl.ucsf.edu > Manage subscription: http://plato.cgl.ucsf.edu/mailman/listinfo/chimera-users

Dear Devs, Apologies for asking a naive question, but i was wondering if there exists a function similar to pymols' get_view and set_view in chimera/chimeraX? If yes, is there a way to do this?

Reading electrostatic potential map in cube format into Chimera
by Boaz Shaanan 30 Apr '19

30 Apr '19

Hi, Does Chimera accept electrostatic potential in cube format (apparently that's what the new Delphi version 8.4 produces). I noticed a cube input under gaussian cube grid, is that the one I should use? Apparently the source of my recent problem with reading an electrostatic potential map had to do with this change of format. I'd appreciate your input.

Deleting data contained in a session
by David Sáez 29 Apr '19

29 Apr '19

Dear Chimera experts: I have saved multiple sessions of molecular dynamics trajectories. Each session is about 5MB. Nevertheless, one of those files is huge, about 120MB. Checking the differences, I noticed that one of the files contained in the session, which normally is a one-frame .pdb, in the large case corresponds to a .nc file, a whole trajectory containing a large number of frames. I did not notice this before because when I opened the .py file, the MD movie box is not shown. As I am only interested in the currently displayed frame of this .nc file, is there a way to delete the additional frames? Some command line trick that would allow me to get rid of the uninteresting frames, and decrease the file size, without having to re-make the whole session again? My most immediate concern is that the file size is too large to be uploaded to a journal online platform. Any help is appreciated, Regards.

Surface representation
by MARIA CLARA BLANES MIRA 25 Apr '19

25 Apr '19

Hello, I would like to know if Chimera could show the surfaces like VMD does with the command QuickSurf (I attach the image with the protein in yellow and the lipids in green). I have been trying with a lot of different variations of the surface command but I can not find the way to make the surface ’softer'…. I have also been trying with spheres representation but the image shows too much information. I need a simplest view, similar to the image because this way it is easier see them move in the .dcd file. It not so important for the protein, just for the lipids. Could you help me with this, please? Thank you very much, clara
