Hello everyone, just a small suggestion to the team. Could it be possible that, when clicking on a given angle/torsion in the Structure measurments panel, the involved atom/bond get selected in the visualizer? cheers JD Dr. Jean-Didier Maréchal Lecturer Computational Biotechnological Chemistry @ Transmet Unitat de Química Física Departament de Química Universitat Autònoma de Barcelona Edifici C.n. 08193 Cerdanyola (Barcelona) Tel: +34.935814936 e-mail: JeanDidier.Marechal@uab.es ----- Missatge original ----- De: chimera-users-request@cgl.ucsf.edu Data: Dimarts, Maig 12, 2009 9:00 pm Assumpte: Chimera-users Digest, Vol 73, Issue 13

I have had bad luck with NVidia drivers packaged as RPMs. Instead I recommend that you uninstall the RPM you got from rpmfusion.org and install the NVidia driver from NVidia at <http://www.nvidia.com/Download/index.aspx>. The "Nvidia.com Binary Installer" option given the webpage you cited. As mentioned there, the disadvanatge of NVIdia's driver is that you need to reinstall it every time your update your kernel -- otherwise the X server won't start. After a successful install (and reboot), glxinfo should tell you which OpenGL renderer you have and chimera should work too.
Good luck,
Greg

Dear Greg, After installing nvidia graphics drivers, i am not able to open chimera.

Then i gave the following command
nvidia-xconfig as root. Then i restarted the system. Now i am able to see nvidia display setting. When i give chimera, it dosent work.

Looking at your chimera benchmark scores and at the scores on the web page, http://socrates2.cgl.ucsf.edu/trac/chimera/wiki/benchmarks, it looks like you don't have the NVidia graphics driver installed. And that would make a *huge* difference. To double-check, run the glxinfo command and look at the "OpenGL renderer string:" line, it should have NVIDIA in it instead of Mesa. To get the NVidia drivers, go to < http://www.nvidia.com/Download/index.aspx>.

I did benchmarks with two chimera versions 1.3 (attached file chim_test)>>> and chimera 1.4 (attached chim_test1). My graphics card is nVIDIA GETFORCE 9300MG, VRAM: 256 MB. I dnt know how to compare and judge what is going wrong. I wud appreciate your help on the same.
Thanks, Bala
So it was formerly fast on the same computer? This could happen on a Linux
computer if you updated the kernel and forgot to reinstall the graphics>>>> driver (from ATI or NVidia, the open source 3D drivers still need work, but are improving). Another possibility, on all operatings sytems, is that there is a background process that is using a lot of CPU or memory, so chimera doesn't have the resources it used to.
If you just want to check the graphics performance, then you can use the Benchmark tool in Tool / Utilities to guage the current performance. And then you can compare to the reported scores to see if your graphics>>>> performance is reasonable (the Show button in the Benchmark tool brings up the web page).

Dear all,
what is the way to add pseubond between metal and chelating atoms? if you could tell me what are the "mouse driven" and "script driven" manner I'll be very pleased.... all the best, JD

Hi: Is there a command in Chimera to protonate (Sybyl-type) the heteroatoms only (or deprotonate the other elements from a fully protonated protein)? thanks francesco pietra

Hi JD, The "user interface" (i.e. no programming) way is to create a text file listing the desired pseudobonds and their colors and read it in with PseudoBond Reader. The tool and file format are described here: <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/pbreader/pbreader.h...
I don't know the python way, but perhaps looking in the code for PseudoBond Reader will help ( share/PBReader/ within your Chimera installation). Best, Elaine ----- Elaine C.

Hi JD, Seems like a good idea. I'll try to get it done soonish. --Eric
