Re: [chimerax-users] [Chimera-users] color by zone in chimeraX

Hi Pranav, I’m Cc'ing the chimerax-users(a)cgl.ucsf.edu list (recommended for ChimeraX questions). I believe the problem is that when coloring the chains you are using “target c” which means to color only cartoons, whereas coloring by zone uses the atom colors. Since you only colored the cartoons, the atoms probably still had heteroatom color-coding. If you use “target ac” instead (even if the atoms aren’t shown), then as long as the color zone distance is big enough, I think you will get the color zones you expect. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#simple> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#zone> I hope this helps, Elaine ----- Elaine C.

Is color command slower in ChimeraX than Chimera?

Hi, I'm testing driving ChimeraX (or Chimera) from Jalview, in particular colouring structures using the Jalview alignment residue colouring. Ideally this should perform well at scale for large numbers of structures and/or colours (for example a graduated colouring based on some property). I've noticed that ChimeraX appears to do this slower than Chimera. Is there a reason, or something I should do to make the command faster? Here's an example like for like comparison using the Chimera/X command line (also attached as a text file): Chimera 1.15 (build 42156) > open cifID:4zho cifID:5h92 cifID:1a70 cifID:4zhp > focus >

creating an annotated structure
by Melissa Jurica 30 Jun '20

30 Jun '20

Can you provide some guidelines for how one could create an annotated structure to share with colleagues? For example, I would like to annotate the cancer associated mutations of a protein, making it easy for someone to select and visualize the associated residue in a structure. Ideally, these annotations could be grouped and sorted. Even better, they could be linked to other resources. Thanks Melissa

Converting Chimera movie script
by Vid Sustar 27 Jun '20

27 Jun '20

The following bug report has been submitted: Platform: Linux-5.3.0-61-generic-x86_64-with-debian-buster-sid ChimeraX Version: 1.0 (2020-06-04 23:15:07 UTC) Description Hello! I have tried to adapt the cliping script from http://www.rbvi.ucsf.edu/chimera/data/movie-howto-mar2012/scripts/clip.cmd to work in ChimeraX (because my structure is too big, to be loaded properly in earlier Chimera) I tried to convert the old commands to the ChimeraX, but I get an error in the line "clip front -0.5 120": Expected a keyword Please advise me how to change the code to work with ChimeraX to create a movie or to simply save a series of images of cliped planes Best regards, Vid Sustar Log: UCSF ChimeraX version: 1.0 (2020-06-04) © 2016-2020 Regents of the University of California.

Hi ChimeraX developers, I have been tryinng to use 2dlabel to annotate some things in a movie. I have stumbled accross a number of problems: 1) creating 2 labels with the same name causes a crasH: 2dlab create ADP text "ADP state" color black size 26 bold true xpos 0.03 ypos 0.92 visibility false 2dlab create ADP text "ADP state" color black size 26 bold true xpos 0.03 ypos 0.92 visibility false

Local resolution legend
by Tetter Stephan 25 Jun '20

25 Jun '20

Dear ChimeraX Users and Developers, I manage to color my cryoEM maps by local resolution, but can't figure out how to display a scale bar of the color code. Any ideas? Or do I have to go back to Chimera for this? Thanks, Stephan

Morph cryoEM maps result
by Aritz Roa Eguiara 25 Jun '20

25 Jun '20

Dear ChimeraX team, This is probably a previously discussed topic but I have not managed to find it specifically anywhere. So I am trying to morph a couple of maps on ChimeraX using the volume morph command, but I do not get any slider as it happens with the atom model morphing (as far as I understand there is not option for that?) Also, once I do it I get a model that is called morph that if I run the movie is recorded but I cannot bounce or control any further, is it like a one time use command that then only leaves that model result of the last frame that cannot be used anymore? Best regards, Aritz

CIF writer renumbers residues
by Daniel Asarnow 23 Jun '20

23 Jun '20

Hi all, When I save a CIF from ChimeraX (while using ISOLDE), the warning "Not saving entity_poly_seq for non-authoritative sequences" is produced, and all the residues have been sequentially renumbered from 1. When there are missing residues, each segment has to be renumbered manually afterwards. Is there some way to avoid this with PDB or CIF inputs? Is it a bug? Best, -da

That seems at the moment neither in ChimeraX 0.93 nor in 1.0 the case, but could be an easy way to add fast a bunch of named selections to the current selection.

Changing to Menu_Mode:Add in Menu:Select seems not to have any effect on that. I think in Chimera1 named selections still could be added to the current selection using the „append“ selection mode. At the moment adding named selections to the current selection works for me in ChimeraX just with the command line „select add“ command. > > > > > > Many thanks for your help, > > > > > > Philipp Milkereit

Re: [chimerax-users] [Chimera-users] convert .mod to .mrc
by Elaine Meng 23 Jun '20

Dear Emmanuel Moebel, I can't think of a simple way to make an index map from IMOD meshes, only a multistep process for each mesh object. At first I misread the question and thought you said "ChimeraX" so below are steps for both Chimera and ChimeraX in case anybody might be interested. I have not tried the entire process, however. I hope this helps, Elaine =-=-= The following instructions are for Chimera: Each IMOD mesh object from the file is a surface piece. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/imod…> You can specify that surface piece in a "mask" command as "sel" (after selecting it with the mouse) and specifying input map as "ones" to create a map that has values of 1 inside, 0 outside. Then you can scale the map by using "vop scale" to multiply values by a constant (e.g. for values of 2 or 3 instead): <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/mask.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#scale> Maybe if you did this for multiple mesh objects you could combine the results into one map with "vop add"; not sure how well this would work. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#add> Then you can save your index map as MRC using the Volume Viewer File menu or command "volume" <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/volu…> =-=-= The following instructions are for ChimeraX. Each IMOD mesh object from the file is a surface model in ChimeraX. <http://rbvi.ucsf.edu/chimerax/docs/user/formats/imod.html> You can specify that surface model in a "volume onesmask" command to create a map that has values of 1 inside, 0 outside, then multiply values by a constant (e.g. for values of 2 or 3 instead) using "volume scale": <http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#onesmask> <http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#scale> Maybe if you did this for multiple mesh objects you could combine the results into one map with "volume add"; not sure how well this would work. <http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#add> Then you can use "save" to write your index map as MRC: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#map> I hope this helps, Elaine ----- Elaine C.
