Dear Smith,

After  you get a segmentation (set of colored surfaces) that you like, you can write a new map that contains only the parts that you want. 

(1) select the surfaces that enclose the parts that you want:  Ctrl-click on one colored surface, then Shift-Ctrl-click on others to add them to the selection

(2) use Segment Map menu "File… Save selected regions to .mrc file"  to save a new density map masked by the selected surfaces.  Also in that menu is a choice to save each surface-enclosed region to a separate map file.

There's also a tutorial on using Segment Map, but I don't see anything in it about map-erasing:

I hope this helps,
