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

Re: [Chimera-users] Display a spider volume data in a specific orientation

Hi Zongli, This is not my area of expertise (our expert is currently out of town) -- at first I thought you could use "Transform Molecule Coordinates" (under Tools... Movement), but now I see that it works only on atomic structures rather than maps: <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/transform/transfor… > It only works on molecular structures because it actually changes the atomic coordinates, without changing the model transformation. I've figured out one workaround, but it is both crazy and slightly tedious: (1) open your map (say as model 0). (2) open any atomic-resolution structure, it doesn't matter what, and open it twice -- now you have three models. Don't move them separately from the map (yet). Let's say the atomic structures are models 1 and 2. (3) use "Transform Molecule Coordinates" with desired Euler angles and shift on one copy of the atomic structure (say model 1). (4) use the match command to superimpose the other copy of the atomic structure on the one that was transformed: match #2 #1 (the command can use the whole models since they should have exactly the same atoms) (5) use the matrixcopy command to apply the transformation matrix of the second copy of the atomic structure to the map: matrixcopy 2 0 You might think "why do I need two copies of the atomic structure? can't I just transform one copy and then use matrixcopy?" ... in fact that's what I tried first, but after it didn't work, I realized it was because the Transform tool works by changing the coordinate values and not the stored matrix of the model. It is necessary to match the second copy to generate a corresponding matrix, and then matrixcopy can be used. I'm CC-ing the chimera-users(a)cgl.ucsf.edu list in case other Chimera users have suggestions. Our expert Tom G should be back next week and he might also have ideas. In general, it's better to send Chimera questions to that mailing list instead of just me, because I could be away from work or (like now) lacking a good answer! I hope this helps, Elaine ----- Elaine C.

font size in pull-down menus
by Boaz Shaanan 09 Oct '13

09 Oct '13

Hi, Is there a way to change the font size of the pull-down menus? For some reason on the Windows (XP) v.1.5.1 they seem smaller to me. Nothing in terms of graphics (or my eyesight) has changed since I upgraded to 1.5.1 recently. Thanks, Boaz Thanks, Boaz Boaz Shaanan, Ph.D. Dept. of Life Sciences Ben-Gurion University of the Negev Beer-Sheva 84105 Israel Phone: 972-8-647-2220 ; Fax: 646-1710 Skype: boaz.shaanan‎

color surface based on NMR Order parameters
by lalit.deshmukh＠huskymail.uconn.edu 08 Sep '11

08 Sep '11

Hello, I like the 'surface color ' feature in Chimera. I think, right now, the surface can be colored by radius, height, volume data and so on.. Is it also possible to color the surface based upon the NMR order parameters or intensity ratios (it will be an Excel file containing just two columns: residue numbers and the respective parameter values)? Or this can be done in some other way? Thanks in advance, Regards, Lalit Deshmukh, University of Connecticut Storrs, CT 06269

Not Responding
by Chad Junkermeier 05 Jul '11

05 Jul '11

Hello, I have been having strange behavior lately with opening coordinate files. I am using xyz format files with up to 500 atoms. When I tell Chimera to open one of these files the computer sits for a moment and then starts reporting that Chimera is "Not Responding." I have tried this on three different Mac computers, one using OS X 10.6.7 (iMac Core i7, 8 GB Ram, ATI Radeon HD 4850) with all of the latest updates, one using OS X 10.6.7 (iMac Core 2 Duo, 4 GB Ram, NVIDIA GeForce 9400), and one 3 or 4 year old Macbook that has (4GB RAM, and I don't know anything else). On each of these machines I have tried using a variety of different versions of your code, and I continually find that I have the same problem. I also just installed Chimera on a Windows XP machine and it has similar issues. The xyz files are the product of relaxing a graphene sheet in Quantum Espresso, and then copying and pasting the final configuration out of the QE output file into a xyz file. Here are a few of the things that puzzle me. First, if I place the input configuration of atoms into a xyz file, Chimera will read in the structures without any problems. The output xyz files work in VMD and in iMol. I thought that it might be an issue with the xyz data structure and transformed it to PBD and it still wouldn't load. I also wondered if it was an issue of too many decimal points (higher precision than the input file), but after reducing the number of decimal points of each coordinate on all of the atoms, it still wouldn't work. I have looked through some of the output files and there doesn't appear to be any weirdness in any of the files. Further complicating this issue is that sometimes, after if I let it sit for a while, the program magically starts working. Again, I have no problem opening other files. Does anyone have any ideas on what to do to fix this problem? Chad

Re: [Chimera-users] Stereo vision with Quadro 600
by William Joseph Allen 29 Jun '11

Hi Greg, I was finally able to figure out what I was doing wrong. On the Nvidia control panel, I was changing the following settings: Stereo - Enable: 'On' Stereo - Display mode: 'Generic active stereo (with NVIDIA 3D vision)' For only specific programs (VMD, MOE, Chimera). That worked for VMD and MOE, but not for Chimera. As soon as I made those settings global, I was able to use stereo in Chimera. There must be other programs, like python.exe or something, that must also be stereo-enabled for this setup to work.

creating a peptide bond between two fragments
by Glenn Millhauser 28 Jun '11

28 Jun '11

Hi Folks, I am trying to add a four amino acid segment to the N-terminus of a protein in the pdb. I can generate the four residue stretch and move its C-term close to the N-term of the structured protein. I can then select the C' and N atoms, which are about 1.0 Angstrom apart. At that point, I am stuck. Not sure how to add a bond and then create a proper structure. I've played around with Join Models, but no luck. Without a peptide bond recognized by Chimera, ribbons are discontinuous. Any ideas? Many thanks, glenn Glenn L.

Capping a clipped sphere representation
by Michelle E. McCully 28 Jun '11

28 Jun '11

Hi, I would like to create an image of a protein shown in van der Waals spheres with a clipped surface. I'd like each individual sphere/atom to be capped and colored the same color as the atom. Is this possible? I can show the protein in spheres and clip it using the side view dialog, but the clipped spheres show up as shells instead of solid balls. I also have found directions for capping and coloring surfaces, but I don't see a way to make the clipped surface colored by atom. It seems that building my protein out of sphere shapes and clipping that would give me the desired effect, but I was hoping there was something easier and built-in that I'm missing. Thanks for your help, Michelle

Stable 64bit version
by Guy Hughes 28 Jun '11

28 Jun '11

Hello, I am an MPhil researcher at the University of Manchester based in laboratory of Professor Bob Ford. I have been using cryo-electron tomography to build a 3D volume containing mucins (High Mr heavily glycosylated polypeptides) which are what my research focusses on. We use a Tecnai 300kV Polara and Gatan's Digital Micrograph software to create tomograms of our samples and then IMOD to view them. Recently I was told that Chimera would be a very useful tool when married with the data from IMOD so I downloaded a copy from your website. I regret to admit that I had several problems with the programme and eventually had to delete. The main problem was that my computer continued to blue-screen and perform very slowly if at all. The labtop I was using has the following spec.; CPU: Intel Core i5 VGA: NVIDIA Geforce 310M/1GB DDR3 RAM: DDRIII 4GB (2GB*2) OS: Windows 7 64-bit Is my PC inadequate or is it possible I downloades a corrupted/unstable version of Chimera? I would very much like to try and start using Chimera again but would first like some advice on what the original problem may have been. Any suggestions or help would be greatly appreciated. Thanks, Guy Hughes.

Dear sir, I want to setup the chimera 1.5.3 program on windows XP system, but the setup cannot be finished, it retures a error information that says: "Unable to excute file: C:/program file/chimera 1.5.3/bin/pythonn.exe." How can I solve the problem? Thanks.
