Re: [Chimera-users] chimera vrml issues...
by Thomas Goddard 17 Feb '06

Hi Janet, The Chimera VRML export only exports surfaces (molecular surfaces, volume data surfaces, multiscale model surfaces). It does not export ribbons or atomic models. Some text in the Export Scene dialog describes this limitation when you select VRML as the File Type. The X3D export is probably the best option. It is a pain to convert but I would try the X3dToVrml97.xslt translator on a machine with more memory if you think that is the reason it is not working. If you don't have a machine available, we can try on one of our machines. Greg Couch here will need to look at the POV and Renderman failures. Tom

Chimera 1.2176: surfaces fail for some structures?
by Anna Feldman-Salit 13 Feb '06

13 Feb '06

Hello, I have noticed that for 1.2199 version there is a "know bug" of surface failure. We have been working with 1.2176 version (which is probably even not release version). Apparently, I have the same problem with some of molecules (working with 1.2176). Is it occasionally or there is a "known bug" for 1.2176 too? Can you maybe recommend some version that has not such a problem? Thank you in advance! Sincerely, Anna.

Chimera on Intel macs
by Eric Pettersen 11 Feb '06

11 Feb '06

The 1.2199 release candidate was compiled for PPC macs and fails on Intel macs despite Apple's emulation software. We are working on compiling natively for Intel macs and will send another mail when an Intel version is available. --Eric Eric Pettersen UCSF Computer Graphics Lab pett(a)cgl.ucsf.edu http://www.cgl.ucsf.edu

labels in Chimera
by Sergey Ryazantsev 10 Feb '06

10 Feb '06

Dear Chimera users I am new in this area, so my question may sound stupid, but anyway. I am using Chimera for 3D model visualization (nothing to do with PDB etc). It's 3D models of biological macromolecules obtained using EMAN 3D reconstruction software. Often I need to compare a bunch of the models at the same time and I need them to be labelled (like 1,2,3,4 etc). I did not find easy way to label multiple objects, so labels would sort of stick to particular object and be independent from the other labels. How also, I could place labels in 3D space, so labels would be at different depth? Any ideas? Many thanks, Sergey. _____________________________________ Sergey Ryazantsev Ph. D.

chimera: gnuplot.py
by John Robinson 09 Feb '06

09 Feb '06

Dear chimera power-users: I can use the gnuplot.py library from the python command line without issue. However, when I try to do the same in IDLE under chimera, I get a broken pipe error. Any suggestions? --John -------------------------------------------- John M. Robinson, M.D., Ph.D. mailto:johnmrobinson@mac.com

Chimera for 64-bit Linux machines
by jbrown 09 Feb '06

09 Feb '06

I'm curious - which production/snapshot release runs best on a 64-bit Linux machine? Also, if the current production releases don't run on such a machine, will there b onee in the near future? Thanks a lot. - Jesse Brown

Stereo on Mac OS X, 10.4
by David Belnap 08 Feb '06

08 Feb '06

Almost a year ago, I asked if there were plans to support stereo on Mac OS X. Greg replied that Chimera could only when Mac OS X supported stereo-in-a-window (see my question and Greg Couch's answer below). There seems to have been some progress on this by Apple. Their "scientific visualization" page (http://www.apple.com/science/ researchsolutions/visualization.html) says: Thanks to its PCI Express architecture, the Power Mac G5 with the optional NVIDIA Quadro FX 4500 graphics card gives researchers 3D stereo-in-a-window capabilities using a CRT display and Stereographics CrystalEyes liquid crystal shutter eyewear and E2Mac emitter. See also http://www.stereographics.com/apple.html. If I buy the NVIDIA Quadro FX 4500 graphics card, will I now be able to run Chimera in stereo on a Mac? Thanks.

That appears to be unlikely because stereo-in-a-window is a feature that is only supported on workstation-class graphics cards (NVidia Quadro, ATI FireGL, 3DLabs Wildcat), and Apple only sells consumer-class graphics cards (NVidia GeForce, ATI Radeon). chimera needs stereo-in-a-window, instead of full-screen stereo, so the scientist can still use the dialogs to control chimera. If we figure out a reasonable way to keep the (mono) dialogs working in full-screen stereo, then we will support stereo on the Mac. (This also presupposes that most of the Tcl/Tk on Aqua bugs are fixed.)

release candidate
by Eric Pettersen 08 Feb '06

08 Feb '06

Hi all, We've put a release candidate (1.2199) on the web. Here's a list of changes and new features: http://www.cgl.ucsf.edu/chimera/docs/ relnotes/1.2199.html . If any of them appeal to you, please download the candidate and give it a whirl and let us know if you find any problems. The main motivation for getting this release out is so that web-fetching PDB files doesn't break in a few months (the previous release is using a legacy URL to the RCSB web site that will likely go away). --Eric Eric Pettersen UCSF Computer Graphics Lab pett(a)cgl.ucsf.edu http://www.cgl.ucsf.edu

DMS installation
by Steven Finckbeiner 06 Feb '06

06 Feb '06

The Dockprep and WriteMol2 files worked like a charm. Could anyone give me any pointers on installing DMS? I have spent the better part of a day following the instructions on the web site and I can't get the damn thing to work. I've gotten this far: 2187 atoms usr/local/lib/dms/radii: no such file or directory Thanks again! "Sometimes, life hits you in the head with a brick."

Re: [Chimera-users] Dockprep and WriteMol2
by Eric Pettersen 05 Feb '06

Hi Steve, Your Googling hit our development documentation, which includes features not in the latest production release and in some cases features that aren't in any release yet. Dock Prep is one of those. We are preparing a release candidate that we anticipate being on the web early next week that will include Dock Prep -- though I can't absolutely guarantee that there won't be an unforeseen hangup that delays it a few days. If you want to use Dock Prep ASAP, I could send you the relevant Python files to drop into your 1.2186 distribution -- let me know. As you noticed, the WriteMol2 module got mistakenly left out of the 1.2186 snapshot, so I would be sending you the files for that as well. The files I'd send you would include one small feature that won't be making it into the release candidate: structures with alternate atom locations will have them pruned to the locations with highest occupancy. --Eric Eric Pettersen UCSF Computer Graphics Lab On Feb 4, 2006, at 4:13 PM, Steven Finckbeiner wrote: > I have Chimera beta version 1 build 2186.
