noeshow
by Randazzo Antonio 27 Apr '09

27 Apr '09

Hi all, I am new of chimera and I am trying to display the NOEs that I have used in my calculations along with the structured I have obtained. With my big surprise I have discovered that in a previous version of the program (MIDAS) this was possible (by the command NOESHOW), but it seems that this features is not supported in this version of the program. Do you have any clue in how to resolve this? Is there a workaround or I have to use another program? If this is the case, which program (sometimes I need to display an Amber restraint file or a Discover restraint file). Thanks in advance for your help

Stereo Monitors
by hsosa＠aecom.yu.edu 24 Apr '09

24 Apr '09

Hi, I was wondering if chimera work with one of these stereo monitors that split the image into two opposite circularly polarized images (e.g. MIRACUBE G170S) so that you can use cheap passive glasses, similar to the disposable ones used in some movies. Also I'll be interested If anybody has experience using these monitors. I think they are under $1000 now for a 17' monitor Best Hernando -- ----------------------------------- Hernando Sosa Dept. of Physiology and Biophysics Albert Einstein College of Medicine 1300 Morris Park Av.

Dear Professor, Thanks very much. I can't find the Color Key icon in my installed Chimera following the step in the link. Is it due to the version I am using?

Hi, I was trying to overlay two volumes one from PDB and other from single particle reconstruction software EMAN (*.mrc). When I open EMAN generated 3D volume and then PDB file, EMAN 3D volume got reduce. However, when EMAN generated 3D volume is only in the 'volume viewer' screen, there is no change. Furthermore, if I press 'center' tab of 'volume viewer' volume became squeeze again. Alternatively, what the best way to overlay and compare two volumes. Thanks in advance for any clue, Priya

transition command

Hi, I found the answer for the transition command. Actually It has been discussed in the forum before. It is in the Experimental features site and under Animation commands. Will try that. Sorry about repeating the question.

transition command

23 Apr '09

Hello Developers, I would like to use the transition command to travel through the radius of an icosahedron surface. The builds and release I have, do not recognize the command 'transition'. Could you please tell me which version/build of chimera I should be using for this command? Thanks a lot, 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

Dear Professor, Thanks so much. I am the first time to use Chimera so I am sorry that if my questions seem to be too simple... Sorry that I didn't describe my question clearly in last post. I had got the figure of 20 frames which are colored by using the command "rainbow models red, blue". Then I saved the figure with the file name a.png. Now I'd like to use the color range to denote each frame in the paper, e.g. color range from red to blue gradual changes corresponds to colors used by model 1 to 20 in the saved figure. Since I don't know what is the name it is should be called in English language, I send you an example in the attachment. Many thanks.

Dear Professor, Thanks very much for your detailed instruction. If I use rainbow models red,blue then can Chimera produce a color panel to denote the colors used?

The default behavior is to use a different color for each "model" (generally each structure file makes one model). It is in the preferences, New Molecules category: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/preferences.html#New%20Mole… > You can use "rainbow" for coloring different models or chains or residues, gradually changing from one color to another. You can use either the "rainbow" command or the "Rainbow" graphical interface. For graphical interface, choose Tools... Depiction... Rainbow. In your case you would want to use the "model" option. You can change the colors by clicking the squares and using the Color Editor. <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/rainbow/rainbow.ht… > Similarly, you could just use the command "rainbow models" to use the default coloring, but there are additional keywords to use different colors. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/rainbow.html> For example, if you really only want red->blue and not all the rainbow colors in between, the command would be rainbow models red,blue Here are the built-in color names: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/colortables.html#allcolors > For asking Chimera questions, please send mail to chimera-user at cgl.ucsf.edu and not to me directly, unless you are sending private data.
