[Chimera-users] Selecting planes using command line

[Elaine Meng]

Hi Prathvi,
I believe you would have to use ChimeraX to do this, not Chimera.  So this answer is for ChimeraX only:

You can select the plane models with Ctrl-click in the graphics window, or you can use the selection checkboxes in the Axes/Planes/Centroids tool (ChimeraX) or in the Model Panel, where you may need to use the disclosure triangles to see the submodels and their numbers.  Or you can just look in the Model Panel to find out the number to specify that model directly in commands without using selection.

You can move them separately from other models in the same was as any other models in ChimeraX. I.e. with "models" keyword of move/turn commands, or with mouse modes that move only the selected and/or clicked models.

Of course, if you do this with the planes defined from the membrane "atoms" from the OPM database, you are no longer using their predicted membrane locations.
I hope this helps,
Elaine
