[MINC-users] cavum vergae

[D. Louis Collins]

Atsuko,

mritotal should be able to work (bring the data/brain into stereotaxic 
space) in linear mode, even with a cavum vergae.  Tests have shown 
mritotal to work even in cases with hemispherectomy.

however, if you want to map the data into stereotaxic space using a 
non-linear mapping to remove the enlarged septum, I don't think that it 
will work.  The non-linear warping is not strong enough to achieve the 
level of deformation needed _and_ the warping procedure needs a 1-1 
correspondance between volumes, and in this case, the septum is split 
in the patient and is a single membrane in the target.
