[chimerax-users] suggestion

[Tom Goddard]

Hi Sergio,

  To make ChimeraX rotate each displayed model about its own center you use the "rotate independent" mouse mode.  The tile command enables that mode.  You can enable it after loading a session with command

	mouse left "rotate independent"

Loading a session file does not restore the mouse modes to what they were when you saved the session.  Maybe it should.  In this case it would be helpful but if you were using some other special purpose mouse mode I suspect you usually don't want the session file to remember that.  I've made a feature request to consider saving mouse modes in session files.

    https://www.rbvi.ucsf.edu/trac/ChimeraX/ticket/8067#ticket

We'll add to the tile command documentation the above command which reenables the independent center of rotation.

  The tile command has an option to control the spacing between models called spacingFactor.  If you type command "usage tile" it will show you all the options

usage tile <cxcmd:usage tile>tile <help:user/commands/tile.html> [models <help:user/commands/atomspec.html>] [columns an integer] [spacingFactor a number] [viewAll true or false] [independentRotation true or false]
    — tile models onto grid

and the command "help tile" will show the tile documentation that says the default spacing is 1.3.  So to make closer spacing you could use

	tile spacing 0.8.

The optimal spacing unfortunately depends on the shapes of your models because the models have different extents along different axes.

	Tom

The tile distribution is still there, but now the entire thing rotates around a common axis. I need to apply 'tile' again to make it work, but this resets all the modifications I made in the saved session (these modifications include those in point 2 below).

I noticed the default puts each panel too far away from its neighbors for my taste, so I need to "move" them to make them look closer to one another.
