hi folks, anyone know if the volume plane tool will support arbitrary orientation of the plane any time soon? -Jeff

Question regarding saving PDB in Chimera
by Pancera, Marie (NIH/VRC) [E] 24 Nov '09

24 Nov '09

Hello, I am using Chimera to fit coordinates into EM density. However I have problems when I save with Chimera as the coordinates that I am saving are not the one I see on the screen. Here is what I do: File Save PDB chose the folder A file name A file type The model that I want to save, i.e the one I see on the screen And then I have to select save relative to model, otherwise I am saving the original molecule, the problem is that I am not sure relative to which model I have to save it. IS there an easier way to just save what I can see on the screen? Thanks, Marie

Zalman 3D
by Miles Pufall 11 Sep '09

Hi Guys - I got a Zalman 3D - it's pretty cool with Coot and Pymol. Your site says the row-interleaved stereo view under camera will work with this monitor, but I wasn't having much success. Do you have some more detailed instructions for this particular monitor? I can drop by and visit with it, or you can come see me if you's like. Thanks! Miles in Yamamoto Lab S574 Genentech Hall

Friends, 1) I downloaded the chimera's today's build and tried to change the nucleic acid representation using..Depiction in Tools. I get the following error. Kindly write me what is going wrong ? TclError: unknown option -width TclError: unknown option -width File "CHIMERA/share/CGLtk/OptionMenu.py", line 15, in __init__ See reply log for Python traceback. Thanks, Bala

substitute single residue
by Andrew P. Hinck 01 Sep '09

01 Sep '09

Dear all, I was hoping to make some single amino acid substitutions in the context of a protein binding interface. I've only briefly poked around, but so far the only way I see to do this is to delete existing atoms/bonds one by one, and then rebuild (the alternate amino acid) atom-by-atom/bond-by-bond. Is there an easier way (like, telling the program to substitute an Asp for a Lys, or something akin to this)? Thanks in advance for any suggestions. Andy Hinck Andrew P.

Centro-symmetric space groups
by Michael Day 01 Sep '09

01 Sep '09

How do you get Chimera to recognize centrosymmetric space groups. If I include the space group on the CRYST1 card of the PDB file all is well for non-centrosymmetric groups but when a center of symmetry enters the picture all bets are off. I'm using Tool->Higher-Order Structure->Unit cell For example adding the space group in column 56 of the PDB P1 as P 1 - all's good P-1 as P -1 - complete nonsense although it recognizes there are two symmetry elements P2 as P 1 2 1 - all's good P21 as P 1 21 1 - all's good P212121 as P 21 21 21 - no problem But; P21/c as P 1 21/c 1 - no recognized symmetry elements and no unit cell expansion.

Thank tou Alaine. The new chimera version works perfect!

movie image resolution
by Anastasia A Aksyuk 28 Aug '09

28 Aug '09

Hi, It is very easy to specify resolution for a saved image, but not for the images used to create a movie. Is there a way to generate a movie or a stack of images with higher resolution then a display screen? I seem to be limited to 1273x870. Thanks a lot, Anastasia
