Hi again,

Pardon for resurrecting another old thread: https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2020-May/001139.html

I have needed to extract selected blobs as separate surfaces (and also separate volumes) recently and found a way to do it within ChimeraX version 1.3 (2021-12-08), here's how:

1. Right mouse → Blob → right click desired blob to color it (any color different from the rest of the volume)

2. Split the surface based on colors: sop splitbycolor #1.2

3. Use the desired split surface to mask the original volume data: vol mask #1 surf #2.2 fullMap true

4. Save as a new volume: save my_segmented_piece.mrc #3

Hope this helps :-)

Best wishes,
