Hi Yehuda, I don’t think you are doing anything wrong; in ChimeraX, the lineThickness option doesn’t work for me either, although it works fine in Chimera on the same computer — we will look into it. Sorry for the inconvenience and thanks for reporting, Elaine ----- Elaine C.

Ca trace

Dear all, I was wondering, is there an option to just show a Ca trace in ChimeraX? If yes, can one modify the width of it? Thanks a lot in advance, Valeria

ChimeraX - Color by Electrostatic Potential
by Maurício Menegatti Rigo 14 Sep '18

14 Sep '18

Hi, is there a way to color the protein surface according to Electrostatic Potential, just like we do with Chimera ("Electrostatic Surface coloring" under "Tools"). The input potential file was calculated with Delphi. Thanks in advance, Maurício Menegatti Rigo, *Ph.D.* Brazil

Saving obj file
by Donghyun Park 13 Sep '18

13 Sep '18

Dear ChimeraX-users, I have a question about saving the scene as obj file. In the traditional Chimera, I was able to generate obj file with texture by simply clicking 'save' button. I tried to save obj file simply by typing *save ~/Desktop/file.obj . *I generated obj file but it does not show texture - basically black &white. I was hoping to find some more information on the user guide but I did not find much. Could somebody please help me with this problem? Thank you, Raphael

Hi, I hope this email finds you well. Thank you for making this page: https://www.cgl.ucsf.edu/chimerax/docs/embedded.html I recently passed my thesis with a lot of aid from that resource page. It has helped us tremendously. May I ask if you are still updating the page? If you are, I would like to repay you by way of recommending an additional resource which could be a good addition to it. Here it is: https://www.webhostingsecretrevealed.net/free-icons/. <https://www.webhostingsecretrevealed.net/free-icons/> I hope you find it useful and helpful as well.

Apply dust command to entire timeseries
by Scott, Brandon L. 10 Sep '18

10 Sep '18

I am attempting to remove small connected components from my timeseries volumes. The surface dust command works well for this, but it only works on one time point at a time, is there a way to script this, or use in conjunction with the vseries play command to apply this to each timepoint? Thanks, -Brandon ____________________ Brandon Scott, PhD SDSMT, Nanoscience

Re: [chimerax-users] [Chimera-users] ChimeraX and crosslinks visualization

Hi Pascal, I enhanced the ChimeraX select command so you can select the crosslinks in a length range. Then you can color the selected ones. For example, select #1.1 minimumLength 30 color sel red select #1.1 minimumLength 5 maximumLength 10 color sel yellow sel #1.1 min 10 max 15 color sel blue The minimumLength and maximumLength options will be in tonight’s ChimeraX builds (available around 5 AM Pacific time).

Hi Pascal, Many features are are still in development, so although we can easily imagine useful features (and we welcome your suggestions), many are not yet implemented. Yes, you can load different sets of crosslinks. The “pseudobond” input format is just plain text specifiying pairs of atoms. <http://rbvi.ucsf.edu/chimerax/docs/user/pseudobonds.html> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/open.html#atomic> Then you can specify the different models (input file -> model) in the “crosslinks histogram” command by their numbers as shown in the Models panel, e.g. crosslinks hist #1.3 crosslinks hist #3 <http://rbvi.ucsf.edu/chimerax/docs/user/commands/crosslinks.html#histogram> Currently there isn’t color-by-length or selection-by-length, sorry. The interaction with the histogram that you may already have seen is that passing the cursor over the columns of the histogram temporarily enlarges the corresponding-length pseudobonds and hides the others. There isn’t control over how wide the histogram bars are. Best, Elaine ----- Elaine C.
