Chimera X commands
by Andrew Waight 14 Jan '20

14 Jan '20

Hello all, I've been an exclusive Chimera user for over 15 years. I have been scripting a lot in python lately and am super excited to learn that ChimeraX is written in python3. I totally want to import some chimera functions into my programs. Problem is, the ChimeraX command syntax seems all new (i can't even really figure out how to select properly, is there a ChimeraX command index that I am missing and is ChimeraX for me? ChimeraX looks beautiful by the way. Thanks you guys are amazing! Drew

Fwd: Downloading HIV PDB 3j3q?

When I try to import it to Chimera it begins downloading, but the molecule never quite appears, even though it ends up in the entry list. The screen stays blue like it has yet to be uploaded. If I try to upload it from the list, again, nothing appears. I realise the molecule is very large, but I think I'm missing something important here? > > Thanks so much for your help, as always, > > Maja > > Dr Maja Divjak > BAppSc(Hons), PhD, Grad Cert 3D Animation (AFTRS) > Biomedical Animator > Office of Cancer Research > Hi Maja, (forwarding to the address that should be used for for Chimera questions) It is probably just too big for the memory on your computer to open this structure in Chimera. Depending on what you’re trying to do with this capsid, maybe you could try using ChimeraX instead of Chimera. It handles large structures much more efficiently, but it does not have the same set of features as Chimera. <http://www.rbvi.ucsf.edu/chimerax/index.html <http://www.rbvi.ucsf.edu/chimerax/index.html>> If you are just trying to get the atomic coordinates of the entire capsid, they are already in the file(s) you could download directly from the RCSB PDB without using any visualization program. <https://www.rcsb.org/structure/3j3q <https://www.rcsb.org/structure/3j3q>> Best, Elaine ----- Elaine C.

Placing a model at 0,0,0?
by Divjak Maja 14 Jan '20

14 Jan '20

Hi there, I'm not sure this is possible, but what I would like to do is edit molecules in Chimera, position them at 0,0,0, save the PDB and then import the molecules into Maya, so that they are positioned at 0,0,0 in the viewport, instead of in some random position away from the work grid. I can actually edit molecules, then position them by eye in the Chimera viewport and save as PDB, which will position them near the grid in roughly the right orientation when imported into Maya. So what I'm looking for is a way of setting the molecules exactly to 0,0,0 in Chimera, so that they appear at 0,0,0 when imported into Maya. I'm not sure this is actually a valid concept in Chimera?

Selecting multiple residues in one chain
by Yehuda Halfon 12 Jan '20

12 Jan '20

HI all, I want to select and color multiple residues in one chain. When I use select #1: 15, 18, 20 .B It select 15, 18 and 20 in all the chains. But when I use select #1: 15.B, 18.B, 20.B It select 15, 18 and 20 in chain B. Is there another way to select residues in one chain without adding .B after each one? It makes the script much bigger and less clean. Yehuda

Hello, I arrive a bit late to the discussion. After the Catalina upgrade, the open button in chimera is greyed out and I cannot open more than one file at any one time. Would anybody have any idea what is wrong? I have downloaded the latest build of chimera. Thank you for your help. Best, Chiara

Dear all Chimera users In UCSF ChimeraX version 0.91 (2019-08-30) I opened a .pqr file (generated with pdb2pqr in Chimera 1.14) and then I opened a .dx file (generated with APBS in Chimera 1.14) Then I input the commands: >surface >color electrostatic #1 map #2 palette -10,red:0,white:10,blue [image: image.png] Is it possible to calculate the red and blue area in Å2 of the molecule?

The answer you got from the Delphi people sounds familiar to me which is why I switched to APBS interface on Chimera (works on both Windows and linux). The .dx file produced by APBS is read and contoured nicely by Chimera. If you need to ionize the structure, there is a Windows PDB2PQR executable as mentioned by Elaine (I understand that you're using Windows).

However, the file you attached was not the ?.phi? file (electrostatic potential map) output from DelPhi. It was just the text output from the DelPhi program. If DelPhi runs successfully on your structure, it will create a separate file, with name ending in .phi, that is the electrostatic potential map. If by ?cube? you mean Gaussian cube grid, Chimera does read that format. <https://nam05.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.rbvi.u…> However, this format is handled simply as a map that is not necessarily electrostatic potential, so it would require more steps in Chimera to get the coloring you want.

The latest Delphi version that I tried (8.4) produced a cube format file which formally can be read and contoured in the Chimera volume viewer. I hated the way the electrostatic surface produced that way looked and abandoned it. Delphi v. 6 which I have (and which I think Elaine used 3 years ago) produced the good old .phi which is file properly displayed in Chimera . I think one can still get hold of V.6 from the Delphi distribution site. To avoid this mess I used the APBS interface of Chimera which worked fine and produced a nice, familiar style, looking electrostatic surface (see for example Fig. S10 in the supplementary of doi: 10.1093/nar/gkz604).

Re: [Chimera-users] Problem with DelPhi in chimera
by Elaine Meng 24 Dec '19

Hello, That sounds like a problem with your DelPhi setup, or you didn’t wait long enough for the calculation to finish. Sometimes it takes several minutes. Instead of DelPhi, you could try using PDB2PQR and then (on the resulting pqr file) using APBS. Chimera has interfaces to both of these: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/apbs/pdb2pqr.html> <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/apbs/apbs.html> …or you can use their web server directly, outside of Chimera: <http://nbcr-222.ucsd.edu/pdb2pqr_2.1.1/> <https://apbs-pdb2pqr.readthedocs.io/en/latest/downloads.html#web-servers> I hope this helps, Elaine ----- Elaine C.

The answer you got from the Delphi people sounds familiar to me which is why I switched to APBS interface on Chimera (works on both Windows and linux). The .dx file produced by APBS is read and contoured nicely by Chimera. If you need to ionize the structure, there is a Windows PDB2PQR executable as mentioned by Elaine (I understand that you're using Windows).

However, the file you attached was not the ?.phi? file (electrostatic potential map) output from DelPhi. It was just the text output from the DelPhi program. If DelPhi runs successfully on your structure, it will create a separate file, with name ending in .phi, that is the electrostatic potential map. If by ?cube? you mean Gaussian cube grid, Chimera does read that format. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#volume> However, this format is handled simply as a map that is not necessarily electrostatic potential, so it would require more steps in Chimera to get the coloring you want.

I contacted the DelPhi supporters and SUGGESTED to use CUBE output format which isn't possible in Chimera.

The latest Delphi version that I tried (8.4) produced a cube format file which formally can be read and contoured in the Chimera volume viewer. I hated the way the electrostatic surface produced that way looked and abandoned it. Delphi v. 6 which I have (and which I think Elaine used 3 years ago) produced the good old .phi which is file properly displayed in Chimera . I think one can still get hold of V.6 from the Delphi distribution site. To avoid this mess I used the APBS interface of Chimera which worked fine and produced a nice, familiar style, looking electrostatic surface (see for example Fig. S10 in the supplementary of doi: 10.1093/nar/gkz604).

I do not know if it is possible to fix the phi file, sorry. The DelPhi files that Chimera can read are from the academic version of DelPhi, as mentioned here: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#esp> If you have some other version of DelPhi associated with a commercial package, maybe the format is different and Chimera does not know how to read it. Linked to the last section of this tutorial, there is an example DelPhi phi file (3eebB.phi) that Chimera can read: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/surfprop.html> I hope this helps, Elaine ----- Elaine C.

I need your assistance regarding chimera. I'm working on virtual docking and need to prepare more than 10k ligands (in a single file as SDF) for docking process. I need to know that if chimera desktop latest version can fulfill my need. If yes please give me a tutorial pdf or video. Regards Waiting for a quick response Asma Tariq
