The mask command is working fine in my tests. It only sets the map
values to zero outside the surface. The values inside the surface are
identical to the original map. If that is not the case for you than use
menu Help / Report a Bug... and provide the exact mask command you used
and explain how you know that the new masked map values are different
from the original map.
This sounds like the right approach to segmenting a subunit. If
instead you had a fit atomic model you could use Color Zone and the
Split button on that dialog.
