Dear FSL users,
I need to set tractography estimation between two supra-thresholded
clusters of fMRI data. I am not really sure how I should do it. There
are two problems.
1st problem
The cluster is in gray matter. I think if it is not soluted I can make
algorithm which will calculate the nearest white matter area where I
will insert my ROIs of white matter (seed, target or part of white
matter where the pathway goes through).
2nd problem
I think this one is worse. Can I simply use this areas of white matter
as seed and target? There is a problem that the tractography accurancy
falls near by gray matter. Or is it more precise calculate global
connectivity and looking only for pathways which are going through both
areas of white matter?
If second one is better which seed should I use for global connectivity
estimation? Only corpus calosum or some another part of white matter?
Could anyone write his opinion, please? My colleagues can not help me
with tractography problems.
Best,
Rene Labounek
