Brilliant! that worked amazingly, well! Thanks Elaine1 Best, Pranav -- Pranav Shah Postdoctoral Research Fellow.

Hi Pranav, I believe that you can:
(1) use the "shape icosahedron" command to make an icosahedral surface <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/shape.html#icosahedron>
(2) then use the "mask" command specifying the map and the surface (icosahedron) that you just made <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/mask.html>
The mask command has a "slab" option to include some distance from both sides of the surface.
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi Elaine, i was wondering if there was an "easy" way to create an icosahedral ring-mask using chimera's shape and mask commands. At the moment, I am creating two icosahedral shapes of big and small radii and them subtracting the small one from the big one, but this results in inconsistent results i.e the mask does not enclose the volume I wish to cover.
