[Chimera-users] isosurface and blobs

[Elaine Meng]

Hi Raphael,
Sorry no, there is no command (or even GUI tool, as far as I know) to count the number of blobs at a given contour level.

There is also no command to measure the area and volume of a specific blob.  There is only the “Measure and Color Blobs” GUI, since to specify each blob you have to pick it by mouseclick.  
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/pickblobs/pickblobs.html>

Commands “measure area” and “measure volume” only measure the whole surface, that is, all of the blobs together. 
Best,
Elaine
