Suggestion re Docking Results
by Philip Crawford 06 Sep '05

06 Sep '05

Hi. I like Chimera and hit a limit yesterday. (Windows version.) We are running DOCK using the ZINC databases, which produces very large output_scored.mol2 files. I tried using Chimera to open and sort one of these. After an hour, I killed Chimera. John Irwin suggested (via the Dock-fans list) that I recommend you set a limit on the size of output file to be opened. An alternative may be to set a limit on the number of records which will be read, regardless of file size. Thanks for a useful product.

changing the rendering of distanced dotted lines
by Boaz Shaanan 06 Sep '05

06 Sep '05

Hi, Distances between pairs of atoms are marked as dotted lines by the 'distances' panel. Is it possible to make those dots bigger by scaling them up somehow so that they are seen more clearly ? They obviously get larger when I zoom in but sometimes I'd rather stay in the zoom-out view but make the dots more visible. Please let me know. Thanks, Boaz

[Chimera-users] Save pdb files only have 5 subunits at 5-fold at virus?
by Jason 04 Sep '05

04 Sep '05

Hi all Is it possible to save pdb files that only have 5 subunits at 5-fold after using mulitscale tools buliding virus paritle. And this pdb file can open at other programs too, ex: DeepView, PyMOL. When I use File/Save PDB chimera can save pdb file, but this file(model) only can show correctly at chinera. If I opened this file at PyMOL or DeepViewit only show the origional 3(A, B, C)chain model thanks Jason

Using the Chimera Tutorial
by Gea-Ny Tseng 31 Aug '05

31 Aug '05

Dear Chimera creators: I am trying to learn how to use Chimera by using your on-line Tutorial. Is there a printable version of the Tutorial and User's Guide? I am not sure how to read the Tutorial and then try out the commands using one single monitor (that is all I have). Or did I miss something obvious? Your help is highly appreciated?

helices display in latest snapshots
by Boaz Shaanan 30 Aug '05

30 Aug '05

Hello, I the latest snapshots (Windows 2143 and linux 2154) helices show up as thin worms when I ask for 'ribbons' under action (they used to look like nice ribbons in previous releases). I found the tools/depiction/ribbons display and managed somehow to change the look of the ribbons (still, they looked nicer before) but failed to change the look of the helices. Where can I do this now ? Thanks, Boaz

[ViewDock] wrong bonds
by Aurelien GROSDIDIER 29 Aug '05

29 Aug '05

Hi all ! I'm currently trying to use the ViewDock plugin to visualize results coming from our in house docking program, which dumps PDB files. These PDBs are them transformed into in a DOCK3/DOCK4 compliant format. First, I should say I haven't seen a clear description of this format, and the script gathering together PDB files is very empirical. The problem I see might come from a mistake of our docking program. Urls to fock3/4 specifications are thus welcome :) Problem context: ---------------- The problem happens when dealing with ligands having several distinct residue numbers or if the docking coordinates do not consist only of a ligand, but also a set of sidechains of its receptor (also with distinct residue number). Problem symptoms: ----------------- The representation loaded using ViewDock show bonds between each and every atoms of the ligand (and the sidechains, if any), no matters their atom type or how far they are. This is kinda of weird, as the representation is perfect when these PDB are loaded from individual PDB files (not using ViewDock). I am a newbie on this mailing list, and unfortunately this problem should be solved withing a few days or so. I would like to apologize in advance in case this help request should go somewhere else. And in case you need a clearer description of the problem (with figures, input files and so on), feel free to contact me either directly or using the ML :) Thanks a lot for your help, Aurélien Grosdidier

problems reading delphi phi map under XP
by Boaz Shaanan 24 Aug '05

24 Aug '05

Hello, When I try to read a delphi phi map under XP I get the error message: Return code: -2147483641 and the program exits. The same map would be read OK under linux and under Win2k. I'm using the latest win32 snapshot (the same happens with the official release though). I would appreciate if you could let me know what has gone wrong. Thanks, Boaz

ATI catalyst 5.7 drivers with R9600SE video card crash winxp when creating surfaces (or running surface benchmark) in chimera-1.2143
by Sabuj Pattanayek 22 Aug '05

22 Aug '05

Hi, I had upgraded ATI's catalyst drivers from 5.4 (or 5.5) to 5.7 for my R9600SE video card under winxp sp2. In Chimera-1.2143 when I tried to create a surface representation or tried the surface benchmark the screen would go black (monitor led goes from green to orange) and the system would crash (no longer responds to pings). Downgrading to catalyst 5.6 fixed the problem. I sent a trouble ticket to ATI. Has anyone had a similar problem with Radeon (non-firegl) cards? Thanks, Sabuj Pattanayek

Re: [chimera-dev] accelerators and stereo
by Eric Pettersen 18 Aug '05

18 Aug '05

Hi Justin, Chimera doesn't have a function to directly save a stereo image. Instead, what you do is save separate left-eye and right-eye images and place them appropriately in your presentation or paper -- for a cross-eye image that would be the left-eye on the right and vice versa. You save the images by bringing up the Side View (under Favorites) and clicking on the "Camera" tab. There is a "camera mode" menu under that tab that lets you select left-eye/right-eye views. Then just use the regular image-saving process. This is also described in the Images tutorial (near the end): http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/ frameimages.html We want to make this easier to do but haven't gotten to it yet.
