2drms
by Bala subramanian 08 Apr '09

08 Apr '09

Friends, Kindly help me with the following queries. 1) How to output the 2drms created for a md. trajectory using MD movie tool. 2) Is there any way to select a square box of a particular length around the molecule and save the image for publication with the desired resolution. I have seen in the chimera archieve that window size can be adjusted. I am not sure if this is the right way to get my job done. Thanks, Bala

Enhancement request Povray
by Marhoefer, R (Richard) 08 Apr '09

08 Apr '09

Dear Development Team, I would like to generate raytraced images without any shadows. The shininess however should be retained. I experimented with modifying the povray output and added the "no_shadow" keyword to all objects included in the file. This did the job. Could you please add a "no_shadow" option to the povray options panel? It would be very helpful.

python scripts
by christopher lau 07 Apr '09

07 Apr '09

Dear Madam/Sir I am new to Chimera and this forum so I apologize in advance if I my question is inappropriate. I want to start writing python scripts such that I can run the script and the color code, orientation, etc of the molecule opened can be automated. Do you know of any good tutorials that teach what commands are available to use in python for chimera and how to run some basic python scripts in chimera? I have figured out enough to open the Python Shell in Chimera, but that is all. An example python script would be helpful. Thanks everyone, Chris Lau

Re: [Chimera-users] Map Morphing questions
by Thomas Goddard 06 Apr '09

06 Apr '09

Hi Julio, While it is possible to rotate models and use Morph Map at the same time there isn't currently a command to do the morph part. This makes it difficult to record an animation since the morph has to be started by hand from the dialog. The turn command would look like "turn y 3 120" to turn around the y axis in 3 degree steps for 120 steps. Here's the Chimera 1.4 (daily build) "turn" documentation: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/turn.html I would like to make a morphmap command so it can be used in animation scripts. Can you explain a bit more your case involving more than 2 maps? Tom Dr .Julio Ortiz wrote: > Hi Tom, > I have been using recently the Morph Map function in Chimera. It is > really helpful!

delay in starting the program
by Eaazhisai Kandiah 03 Apr '09

03 Apr '09

Hi Chimera-Developers, Recently, my work-computer was upgraded from MaC-OS 10.4 to 10.5. I installed the Chimera X-windows version for 10.5. Apparently, while starting the program, it takes almost 2min for the program to get activated. While checking the activity monitor, chimera tries to use 'OSASCRIPT' which together with Chimera, showed as 'not-responding'. I couldn't troubleshoot the reason for this huge delay in start and hence rectify it. Any help would be appreciated. Thank you, Eaazhisai Kandiah Laboratory of Structural Biology NIAMS, National Institutes of Health, Room 1511,Bldg 50 9000 Rockville Pike, Bethesda, MD-20892 kandiahe(a)mail.nih.gov Off: 301 451 2281 Fax: 301 480 7629

chimera help
by Terrance Chiang 02 Apr '09

02 Apr '09

Hi, I am trying to show a structural change between two proteins that differ by one amino acid, is this possible with chimera? I was unable to display the transformation I desired, so I looked into other ways to show changes between two overall similar molecules. I found that it is possible to show a change in the surface between two similar molecules, but I am unable to utilize the function because it requires a different file format. I would like to do both... that is, to show the conformational change from one protein to another, as well as show the change in surface from one protein to another, but I keep hitting these road blocks. Any help would be highly appreciated! Thanks, Terrance Chiang
