Saving stereo pairs
by Gyunghoon Kang 14 Jun '19

?Hi, apologies if this information is available somewhere but all my searches returned information for the original Chimera. Is there a way to generate stereo pairs either in the command line or GUI? Best, Gyunghoon Kang

Hi there, Is there a way to set silhouettes false for volume meshes, but keep it true for other object types (ribbons, surfaces,...)? Cheers, Alexis

SMILES Input With ChimeraX
by Victor Blaga 05 Jun '19

05 Jun '19

Hello, I am just wondering if there is a way to input a SMILES string with ChimeraX, as with Chimera? I can't seem to find it in the documentation so I just want to confirm this functionality has indeed been dropped? Thank you, Victor Blaga Research Assistant McMaster University Department of Biochemistry and Biomedical Sciences

equivalent command for coloring elements specific colors?
by Liz Kellogg 30 May '19

30 May '19

Hi, There used to be this handy command in Chimera to color oxygen atoms and nitrogen atoms specific colors: color @O red,a color @N blue,a but I can't find the corresponding command in ChimeraX. Is there a way to color all nitrogen atoms blue and all oxygen atoms red? When I try what I think the equivalent command should be (I'm displaying cartoon backbone with stick side chains): color @O red target a color @N blue target a it says 'Colored 1120 atoms' but none of the sidechains are colored differently. Thanks for the help Liz

crossfade warps image when transitioning
by Liz Kellogg 23 May '19

23 May '19

Hi all OK I have a real problem this time (not a silly problem on my end). I'm trying to make movies in chimerax, and I used to be able to use the crossfade function in Chimera to smoothly interpolate two images to change the scene. However, in ChimeraX, when I use the crossfade function it either warps the first image or it somehow interpolates a zoomed in view of the lower left corner of the first image into the second, which makes for a jarring transition. Closing and re-opening ChimeraX seems to change the behavior, but I still can't get a smooth transition between image 1 and image 2. Any idea how to fix this? I thought perhaps setting the view size before starting to record the movie would help, but that doesn't seem to work. Thanks a bunch. Best Liz

nucleotides command not found in chimerax
by Liz Kellogg 22 May '19

22 May '19

Hi ChimeraX users, I am dabbling around in ChimeraX, and it seems that the documentation doesn't quite match up with the commands that are available. For example, this command: nucleotides https://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/nucleotides.html would be useful, but when I enter this into the command line it says "unknown command" I downloaded the nightly chimerax build for mac, so it can't be a problem with an out of date version. Is this command not currently implemented? and if not, how many commands are listed in the documentation that aren't implemented? Best Liz

Re: [chimerax-users] tile command in chimeraX

Hi Elaine, thanks for the quick reply. my usual routine with 3D models involves loading tens of them, match them (now align :P) and then "tile", so yes its a bit tedious. I'll keep doing this in "old" chimera, and look forward for the advances in chimeraX. thanks again for the tool!! francois On Mon, 20 May 2019 at 19:25, Elaine Meng <meng(a)cgl.ucsf.edu> wrote: > Hi Francois, > Not a dumb question, but sorry, there is no “tile” equivalent in ChimeraX > currently.

If you don’t have too many structures, you could first superimpose them all in the middle, zoom out somewhat (“zoom” command) and then translate them individually up/down (y axis) and left/right (x axis) with the “move” command, but it would be a little tedious and require some trial and error as to spacing.

Hi, sorry for the stupid question, but I spent quite some time searching for it. Is there some alternative to the "tile" command in chimera X? thanks! great tool :) francois -- François Serra *senior researcher - comparative epigenomics* Computational Biology Group - Barcelona Supercomputing Center (BSC) C/ Jordi Girona, 29 08034 Barcelona Tel: +34 934 137 97

smoothen coils
by Gabor PAPAI 13 May '19

13 May '19

Dear developers, I would like to show helices as tubes (this I know how to do) and coils between them with smooth trajectories, more schematic, as it is drawn in Chimera using Pipes and Planks (or even more). I would appreciate your help! Best regards, Gabor --- Gabor Papai IGBMC Integrated Structural Biology 1, rue Laurent Fries, Bp 10142 67404 Illkirch, France Tel: +33-3-69485288
