[Chimera-users] generating symmetry mates of a surface model created with shape command

Hi Carmen,
The shape surface is only a surface, not a density map.  Maybe you could do something more elaborate, like use the surface from “shape” as a mask on some other map with the “mask” command (maybe not important which map, as long as you can display an isosurface of the desired shape?) to create a new map, then save the new map as a file, and use some external program to apply the symmetry to that map.  Then read the processed new map with symmetry copies, show isosurfaces now with symmetry copies, and THEN finally do the masking you had wanted to do in the first place.

I don’t know if that would work, and it may be more trouble than it’s worth!
