Re: [Chimera-users] question about AutodockVina /CHIMERA

Hi Osvaldo, Without more information, I have no idea, sorry. If you are sure that the process finished (click the “i” icon near the bottom right corner of the Chimera window to make sure), I can only say to check in the Reply Log (open from Chimera Favorites menu) and see if it says anything else useful. The Autodock Vina process does not run on our system, so there is nothing I can check here; Chimera just has an interface to send and receive results from a web service that is run by another lab, as explained in the help page: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/vina/vina.html> For the future, please send Chimera questions to the chimera-users(a)cgl.ucsf.edu address (CC’d here) to ensure they come to our attention. I hope this helps, Elaine ----- Elaine C.

MD movie residue network analysis
by Neha Gandhi 22 Jan '18

22 Jan '18

Dear List, I am loading gromacs trajectory in Chimera using .tpr and .xtc files. The residue number in gro file starts from 83 and not from 1. When I perform residue network analyis using chimera and cytoscape, the numbering of residues starts from 1. Is there a way to change the residue numbers either in .tpr file or in cytoscape? Changing the residue numbering after the trajectory is loaded doesn't help. Thank you for your attention. Regards, Neha -- Regards, Dr. Neha S.

Inactive atoms
by Nazahiyah Rodzli 22 Jan '18

22 Jan '18

Dear Chimera Users, My Chimera seems to display atoms and side chains in dimmed dark colour (picture below). I’ve tried to change the colour but they don’t work. I also can’t select any of the atoms/sidechains by mouse click+ctrl unless I pick select all from the select menu. I am using Chimera 1.10 version. Could you help me how I can change the settings perhaps? Best regards, Naza

Rotate and transform command
by 大帅 22 Jan '18

22 Jan '18

Hi, Therefore, we used UCSF Chimera to have a map's smmetry axes (approximately) parallel to the XYZ axes. The procedure followed by the relion tutorial we used for that was to read in InitialModel/symC1/run_it003_class001.mrc; use the duplicate option under the File menu of the Volume viewer. Then to deactivate map #1 on the Model Panel; rotate map #0 to have it’s symmetry axis more or less parallel to the XYZ axes; and then to use in the Command Line entry field: run_it003_class001.mrc; and save this model in the InitialModel/symC1/ directory with the name inimodel.mrc I have done as the above tutorial in relion, but the saved inimodel.mrc file does not change its position or orientation at all. So, my question is what commend can save a map after rotating or transforming its x,y,z coordinate ? What is the procedures to do so ? Thanks Dashuai

Command line selection in Chimera
by Jerry Honts 16 Jan '18

16 Jan '18

Is there any easy way to select *a range of chains* in complex models like the ribosome in Chimera at the command line? I haven't been able to work out the syntax for this type of complex selection at the command line. For example, what is the syntax of the command to select chains 1G through 1Z and chains 10 through 19 in PDB file 5DOY [without explicitly listing them one by one]? I may be missing something simple, and I have not been able to get it to work or find an example in documentation. I have been able to do this in Chimera X but not the current version of Chimera. Thanks, Jerry E. Honts -- Jerry E. Honts, Ph. D. Associate Professor of Biology Drake University 2507 University Avenue Des Moines, IA 50311-4505 Science Connector Building 210 (faculty office)

Re: [Chimera-users] Pseudobonds in mmCIF
by Elaine Meng 16 Jan '18

16 Jan '18

Just for the benefit of the list, the problem with spurious bonds between residues in Chimera was solved by adding sequence information to the input mmCIF file.

Those problems are a major reason why we wrote ChimeraX. So please check out ChimeraX, http://www.rbvi.ucsf.edu/chimerax/. The mmCIF reader is several orders of magnitude faster than Chimera's and presents the author numbering to identify residues instead of the internal mmCIF numbering. The graphics in ChimeraX are better too. If there is some feature in Chimera that isn't in ChimeraX yet that you need, please let us know. ChimeraX also works with VR headsets. > > And while ChimeraX shows your structure "correctly". It could do a much better job if the missing sequence information were in the mmCIF file. In Phenix, that is done by running the mmtbx.prepare_pdb_deposition program, i.e, by preparing the mmCIF file so that is suitable for submission to the PDB. That would probably help Chimera too. > > > > HTH, > > Greg

Does Chimera support stereo with a Nvidia Quadro M4000 graphics card?
by xzhang1999＠zju.edu.cn 13 Jan '18

13 Jan '18

Hi, Does Chimera support stereo on the Nvidia Quadro M4000 graphics card? I have a workstation with a Nvidia Quadro M4000 graphcs card (64bit, win10&ubantu), but cannot successfully have Chimera displaying sequential stereo? Any suggestion would be greatly appreciated. Thanks a lot. Best regards, Xing

Output of distance measurements
by Marco Sette 13 Jan '18

13 Jan '18

Dear all, I have a very primitive script to measure distances, like distance :1.a@ha :5.b@ha distance :1.a@ha :4.b@ha distance .... etc. I run the script in File --> Open and get the distances in the Structure Measurements panel and then Save. The output file list all the distances but, for my analysis, it would be better to keep the lines separated by a blank line, or something like this. Maybe this is possible by some change in my primtive script but I have no idea... Thanks for your help, Marco
