[Brains-users] Re: [Fwd: brains automatic volumes]

[Eugene Zeien]

Tara,
	vent2_box is a later refinement of the extraordinarily crude
ventricle_box.  The intent was to cover the lateral ventricles while
including far less peripheral tissue.  The original ventricle_box
will include all of the lateral ventricles even when severely enlarged.
vent2_box is appropriate for subjects who do not show marked ventricular
enlargement.  In either case, only csf volume is usable.

To visualize the talairach box, try converting it to a mask.
