Stereo glasses
by Jonathan Sheehan 13 Jun '19

13 Jun '19

Hi all, What stereo setup are people recommending these days? It seems that NVIDIA has discontinued the 3D Vision 2 goggles+emitter. Is there something else that is available and works well? Thanks for any advice! -Jonathan

Script to generate and fit structures
by Ahmad Khalifa 12 Jun '19

12 Jun '19

I want to write a script that can copy combine my structure, translate it up, down, left or right a certain distance, fit it into its new place. Is it feasible, how can I do it? Regards.

counter ions

Dear All I would like to use counter ions of nucleic acids not included in the default list of Chimera. I do not know how to perform this action. The option add ions offers only a limited set of ionic species I guess that is necessary to use amber18. Can you give me some suggestions Dr. Patrizio Arrigo CNR SMAC

Chimera silent installer options for RHEL 7.6
by Darin Lory 11 Jun '19

11 Jun '19

Chimera Gurus, Are there linux silent install options for the Chimera so I can specify the installation directory, etc. I have chimera working via the regular installation method. My team and I are trying to automate the installation via Ansible playbook. Kindly advise, -Darin "The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!'

Chimera - can I tweak the red color on the Red-cyan stereo view
by Tweten, Rodney K. (HSC) 11 Jun '19

11 Jun '19

We are displaying our protein structures on a large TV in the Red-Cyan stereo view, which works pretty good for 3D viewing (except the required loss of specific colors). We tend to see a bit of ghosting of the red structure, which I suspect is that the red color lens of the Red-Cyan glasses we have (we’ve tried a few with the same results) is not quite matched to that being used by Chimera in its Red-Cyan stereo view. I was wondering if there is any way the user could tweak the red color being used by chimera in this stereo view to more closely match that of the glasses (assuming that this is responsible for the ghosting of the red structure). Thanks!

APBS
by Karl R Voigtritter 11 Jun '19

11 Jun '19

Hello, I am trying to display an APBS surface. I loaded a .pqr file that was generated using the http://nbcr-222.ucsd.edu/pdb2pqr_2.1.1 server. I then ran the APBS tool in the surface/binding analysis tab in Chimera. I left everything to default and clicked OK. It launched the executable and then executed it. The newly generated files came into the Surface Color window correctly. Upon trying to color the surface with the "color" nothing happens. -Karl Voigtritter, Ph.D. California State University, Chico

Regarding MD simulation
by Divakar S 10 Jun '19

10 Jun '19

Hi, I have been trying to do MD simulation in chimera. However, i could not understand the exact procedure from the user help menu. Plz give us a detailed procedure for simulation and analysis if possible. I also tried to learn the procedures from previously published papers but i couldn't find any articles using MD simulation from chimera. Thank you -- *Dr. Divakar S, M.

viewing same size atoms within multiple molecules
by Andrew Garven 10 Jun '19

10 Jun '19

Hi, I am trying to implement a script so that each individual atom in each molecule I view on chimera is the same size (ie each carbon atom i view, regardless of the size of the molecule views a the same size). I realize this must be a function of the scale factor which changes the size of the molecules to appropriate viewing size. Is there a way to properly scale each molecule so that they have a standard atom viewing size. I would appreciate any help in this regard. Andrew

voxel coordinates
by Andrew Garven 07 Jun '19

07 Jun '19

Hi I am trying to get a voxel encodings (coordinates) of molecules that are run through Chimera, as a deep learning model will have an easier time with such data. I am unsure how to retrieve such data from chimera. Any help would be greatly appreciated Andrew

Re: [Chimera-users] THANKS! Chimera question

Hello, Thank you to all of you for getting back to me so fast. Thanks for the help. I am looking forward to ChimeraX Best, Mike de la Flor, CMI Board Certified Medical Illustrator PhD Candidate Biology and Biochemistry Natural Sciences and Mathematics University of Houston From: Greg Couch [mailto:gregc@cgl.ucsf.edu] Sent: Thursday, June 06, 2019 1:28 AM To: Mike de la Flor; UCSF Chimera users mailing list Subject: Re: [Chimera-users] Chimera question 1f16 is a NMR structure and as such has 20 different variations of the structure. Using the command line, you can hide all except for the first structure with the command: ~modeldisplay #0.2-20. To do that graphically, bring up the Model Panel, then click on the group/ungroup button to show controls for the individual structures. Then select the structures you don't want (click, drag, control-click, and shift-click as appropriate), and click on the hide button to leave the one you want.
