nope, that's why we do the surface deformation after the wm segmentation -to correct this type of inaccuracy. On Wed, 18 Apr 2007, Turner, Jessica wrote:
Hi there experts-When we load up wm.mgz with the lh.white and rh.white on one subject, the white matter mask overlaps into the the gray matter ribbon (see attached). When we look at the T1 underneath it, the red and green lines look just fine, but the white matter mask is a bit generous. Do I need to clean that up?
Thanks,
Jess
