[chimerax-users] multiple isosurfaces for one map

[Elaine Meng]

Hi Daniel,
Yes, often more than one isosurface is shown for a given map, and besides or as an alternative to making the outer one transparent, you can use the mesh style.  The Volume Viewer tool's context menu  (shown with right-click, except on Mac Ctrl-click) includes choices to add or delete thresholds, i.e. contour levels.

Or it can be done with commands, as in the first example in the "volume" command documentation:
<http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html>

volume #1 style mesh level 0.8 color red level 1.2 color 0,50,80

I hope this helps,
Elaine

The work-around is to load the same map twice into two different models, but that will take up more memory and is more cumbersome.
