[Chimera-users] how to mask irregular shape in EM density map

[Tom Goddard]

Hi Sy,

   You could trace curves around your object in a few planes to define a 
surface and use that surface to mask the map.  Or you could try a 
watershed segmentation mouse mode.  What works depends on 
characteristics of the actual data.  Videos showing these two techniques 
are on the Chimera web site under video tutorials:
