Hi fsl-gurus,
I have 2 questions re the probtrackx network mode:
Say I have a Region A, B and C defined as masks and enter them as
Multiple seed masks.
What connections will be shown to me:
1) Any connections between A and B, A and C, B and C or 2) just
connections that connect all of them, i.e. A-B-C, A-C-B and B-A-C.
Assuming it is (1), and looking only at connections between A and B.
As I understand from previous discussions, tracking samples are send
from A to B and B to A and only those that reach their target in both
conditions 'survive'.
What I'm wondering about is what are the constraints regarding that:
Does the sample has to go the exact same voxelway to be found valid or
is it rather an overlay where voxels survive that were passed from
either direction, i.e. at least one sample passed from AtoB AND BtoA.
Thanks, Michael
