Command line doesn't work properly on Mac
by Li, Leon 04 Sep '16

Hello All, The command line in Chimera seems not working properly on my Mac. Any input in the command line will not show unless you select them. Does anybody experience this problem? Or any idea about this? Both versions of 1.11 and 1.11.1 have been tried. My mac is iMac (Retina 5K, 27-inch) OS X EI Capitan. Thanks, Leon

Dear Chimera Users, I am wondering if anyone can help me with this question: Whenever I start up CHIMERA. My previous settings and panels show up. Is there a way to prevent my previous preferences being saved? Thanks, David

Deleting invisible structures?
by max taylordavies 31 Aug '16

31 Aug '16

Hello all, Is there any way to selectively delete the 'invisible' (undisplayed) parts of a structure and keep the visible parts without having to use the usual atom-spec approach? For example, if I run per-model clipping on a protein, is there any way to delete the part that has been rendered invisible by the clipping? If this isn't possible, is there a way to export only the visible/displayed components of a scene? Many thanks in advance, Max Taylor-Davies

Integrating chimera into a database
by McCafferty, Caitlyn (NIH/NEI) [F] 29 Aug '16

29 Aug '16

Hi, I have a number of colored protein structures from chimera that are saved as python files. I would like to put these structures on a database so other users may access them. Is there a way (preferably using html) that a user could click on the python file and it would open up in chimera through the database-- even if the user does not have chimera installed? Thank you, Caitlyn McCafferty Postbaccalaureate Fellow Ophthalmic Genetics and Visual Function Branch National Eye Institute Bldg. 10 Rm. 6-3350 Tel: (301) 402-7058 Email: caitlyn.mccafferty(a)nih.gov

bond formation
by A G Szabo 26 Aug '16

26 Aug '16

I am working with a PDB file that has two proteins docked together. As this is a model the two proteins do not have a bond between them. The model number is the same for the two chains designated A and B. I have looked through the various tutorials, functions and tools to figure out how to actually place a bond between two residues that link the two chains. It is well established as to how the two proteins would be linked if the bond had been formed. The linkage is between the S of a Cysteine and carbonyl carbon at the C-terminal of the other protein. I think I have managed to select both atoms, but cannot determine how to include a bond. Your assistance is appreciated. Arthur Szabo

Creating and saving Multiscale Models using Python functions
by Jon David 24 Aug '16

24 Aug '16

Hi Friends, I would like to use Python to perform operations equivalent to the following GUI operations; I'd like to be able to do this as a batch script (e.g., I don't want the Chimera GUI to appear because I don't want to have to close it.): 1) Open a PDB file (I know how to do this part). 2) Tools > Higher-Order Structure > Multiscale Models (this opens the MultiScale Models popup window). 3) Click on the "Make models" button. 4) File > Export Scene... (this opens the Export Scene popup window) 5) In the Export Scene popup window, select File type to be "OBJ [.obj]", enter file name "test.obj" 6) Click on the "Save" button. I have used Python to open a PDB file, and translate, and rotate it around before. But I don't know where to begin with selecting Multiscale Models' parameters. Any tips? Any help would be much appreciated. Thanks, --Jon

volume viewer - planes
by Michael Elbaum 24 Aug '16

24 Aug '16

Hi. I'm using the volume viewer and the Planes function is extremely useful in order to see a subsection of the volume. Often I want to compare different processing or filtering of the same dataset. When I load several datasets, all the visualization parameters are set individually. Normally this is good, for example in setting different colors, but for Planes it's problematic. In order to switch among the various representations and see the same section of the volume I have to scan them individually, and when two are visible I can move only one. Is there a way to link the Planes among the maps? Perhaps there's a command line trick? thanks, Michael

question
by A G Szabo 23 Aug '16

23 Aug '16

I recently downloaded the new version of Chimera. No issues with that so far. However, when I save a session it is still saved as a Chimera file, or a PYC file on my desktop. So when I went to my desktop file list, and tried to open one of the files I would click on "open with ." Two programs would be listed, Adobe, and Chimera. So I would select Chimera and the file would open satisfactorily. However, with the new version of Chimera, if I repeat the above, the only program that is listed is adobe. If the file type is listed as Chimera, then adobe would be listed, and there would be other programs listed but not Chimera. I can open the file in a round about way, but the former way was more efficient and user friendly. If I go to my programs list, there doesn't seem to be a way that I can conveniently open the file without first opening up Chimera. Your comments will be appreciated. Arthur G. Szabo

Select Non-conserved residue
by Markus Heller 23 Aug '16

23 Aug '16

Hi all, I used matchmaker to align two homologues proteins, and to calculate the sequence alignment. How can I select all non-conserved residues, in one fell swoop?
