[chimerax-users] Missing features in ChimeraX

[Tom Goddard]

Hi Junha,

  Glad to hear you are trying VR with ChimeraX.

  Per-model clipping in ChimeraX is done with the clip command, or with the clipping mouse modes, atom radii are set with the size command, visibility is set with the show/hide commands, color is set with the color command, there are volume tracer mouse modes, and saving marker files should work, although you hit some bug and should press the Report a Bug… button when you get that traceback.  ChimeraX does not have the selection inspector window yet.  ChimeraX uses a different window toolkit Qt while Chimera used Tk so it requires all new code to move any graphical user interface from Chimera to ChimeraX.  ChimeraX is a completely new program, modernizing every component of the 20-year-old design of Chimera so even moving commands from Chimera to ChimeraX requires substantial work.

  If you don’t find ChimeraX ready for your use, of course you should continue to use Chimera.  We expect ChimeraX to replace Chimera in a few years.  You might want to spend an hour skimming Elaine’s thorough ChimeraX documentation to understand what is in ChimeraX, including many new features like virtual reality that are not in Chimera.

	Tom
