chimera for linux ppc
by Alex Zelter 07 Dec '05

07 Dec '05

Hi, I was wondering if it would be possible for the developers to compile a binary version of chimer for use on linux ppc architecture seeing as it is not possible for a user to compile for themselves due to the proprietary solvent-accessible molecular surfacing library. I know this is not a common architecture, but some people do use it. Thanks in advance, Alex Zelter

Missing tools
by Luke Kontogiannis 07 Dec '05

07 Dec '05

Hi all, I installed chimera on windows and everything works fine. However, I installed it on ubuntu linux 5.10 yesterday and there are some tools that are missing such as multiscale. Is the windows version of chimera simply more capable or have I done something wrong? I simply ran the chimeral.exe file as root and it seemed to install fine. I even tried replacing the share directory on the linux box at work with the one from the windows version but that gave errors upon launching. Any ideas? Thanks Luke

Dear all, I have learned that 3D results/data from molecular dynamics or docking can be compressed to produce informative 2D diagrams for publication. Can anyone recommend such a program? Thank you and good day "Its hard to hold on to something that can never be yours in anyway you want... something that wasnt really yours to begin with... you just have to go on and accept the fact that while good things never last some dont even start...."

Add hydrogens to get -NH2 group
by Daniel Svozil 02 Dec '05

Hi all, if I use addH tool on the C-N, I would expect to get C-NH2, but I get C-NH3 instead. How should I proceed to get C-NH2 correctly?

Sequence alignment
by David G. Morgan 01 Dec '05

01 Dec '05

Hi, I'm learning to use the sequence alignment tools in chimera. I know that I can highlight sequences in the alignment window and select residues in the structure, but is it possible to do the opposite? In other words, I'd like to box or otherwise select some residue(s) in the structure and have that region highlighted or otherwise marked in the aligned sequence window.

Feature Request: Expose rotation to python
by Charlie Moad 29 Nov '05

29 Nov '05

The repr of an xform shows the opengl rotation matrix. I want to get this efficiently in python, but I don't believe it is exposed. Could a getter please be added returning a 4x4 tuple, so a Numeric array can be trivial/efficiently made from it? If there is a current approach please let me know. Thanks, Charlie

estimaded standard deviation (sigma levels) for electron densities in volume viewer
by Pattanayek, Sabuj 28 Nov '05

Hi, Is it possible to specify the estimated standard deviation (sigma level) for electron densities in the volume viewer? Currently, I have to eyeball the distribution of the volume data and place the bar accordingly. Thanks, Sabuj Pattanayek

Question about connectivity
by Frederick Gimble 22 Nov '05

22 Nov '05

I have just begun using Chimera on my Mac, and find that it will be able to produce the graphics that I need for publication and display purposes. I recently opened a pdb file of a protein that we study bound to DNA and used the depiction, nucleotides tool to render the DNA backbone as ribbons with the bases shown as slabs. I noticed a discontinuity in one of the DNA strands, which may be caused by the severe distortion of the DNA. I think that this also happened with a previous program that I used called SPOCK that I used to draw the DNA strands as worms. In that case I could repair the break by changing the settings for the connectivity distances. How would I repair the break in Chimera? Thanks for your help. Sincerely, Fred Gimble Frederick S.

Chimera failed abnormally
by Johan Börjesson 22 Nov '05

22 Nov '05

Hi I have downloaded the chimera-1.2184-win32.exe version of Chimera and installed it on my laptop running on an Celeron M 370 processor. The operation system is Windows XP. The problem is that I get an error message when I try to run the program. Chimera failed abnormally; the exit code was: 1. use the --debug command line option for the full error message. Hope that you can tell what the problem is and what I can do about it. Best regards Johan Börjesson Dept. of Biochemistry Lund University, Sweden

Move atoms (selections) in Chimera
by Daniel Svozil 21 Nov '05

21 Nov '05

Hi, is there any possibility, how to move atoms (selections) in Chimera? If, e,g,, I want to make C-H bond a bit longer? move command seems to work only with model.
