Compiling chimera from source code
by cdlau＠ucsd.edu 13 May '09

13 May '09

Dear Madam/Sir, I am currently involved in a project which requires compiling the Chimera source code from scratch. I have been using: http://www.cgl.ucsf.edu/chimera/sourcecode.html for reference, and I understand that surfacing library is not available due to licensing issues. Because I am not interested in using this feature, I wanted to know if it was still possible to compile the Chimera source code. I know that it will be difficult but any knowledge or past experience that may help me would be greatly appreciated. Thanks in advance, Chris

Friends, Is there any way to check the performance of chimera. I have been using chimera without any problems but now it is very slow, in opening even a small dna molecule and manipulating. Is there any way that i can check the root of the problem. Thanks, Bala

Coulombic Surface Coloring

Hi: I would like to simply color the surface of a protein by the Coulombic Surface Coloring method. I can show the surface, have a file with calculated charges if useful, but i am unable to implement the indications below "There are several ways to start Coulombic Surface Coloring, a tool in the Surface/Binding Analysis category. The molecular surface(s) should first be displayed (using Actions... Surface... show or the command surface) and then chosen from the list of Surfaces to color by ESP. " which tool should be opened from Surface/Binding Analysis? Of those related, I can only see Electrostatic Surface Coloring and that - in my hands - does not bring to the simple Coulombic method. Thanks for clearing francesco pietra

My Chimera 1.4 build 27395 is not keeping 2D Labels when saving images except if Pov-Ray tracing is turned on

Hi When I save a picture with 2D Labels, they don't show up in the saved image. I tried with different image types (jpg, tiff, png) and even a new image just with some 2D Labels in it. I don't know if this is important but all of them have a white background. The only way I managed to see the labels was to turn on Pov-Ray tracing! Any ideas? Thank you in advance Victor Alves

creating volume maps
by Nils Becker 29 Apr '09

29 Apr '09

Hi, I would like to use chimera for measuring the steric accessibility of particular atoms in a structure to reactive species in solution. To do that I had the following idea: 1. create a volume map which represents a solid sphere centered on the atom in question (alternatively, a Gaussian blob), with some chosen radius. 2. mask this sphere using the solvent accessible surface of the protein (for example, if the atom is at the surface and the surface is flat, half of the sphere would be cut away) 3. measure the volume of the remaining piece of the sphere. So now my question is: can this work, and how can I generate the sphere in step 1. ? thanks for any advice! Nils

In Chimera 1.4 (daily builds) this is unnecessary and your original script works correctly because in 1.4 movie encode does a movie stop implicitly. Tom

noeshow

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.

Re. Volume squeeze

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
