What regions are you trying to track between? Have you verified that your
diffusion lines are properly oriented?
Peace,
Matt.

Subject: [FSL] interhemispheric tracking
Hi,
I am finding difficulties running probtrackx with a seed mask in one
hemisphere and a waypoint in the other. In most subjects, the pathway does
not "find its way" across.
I am using a hemispheric mask with a decently sized "window" around the
corpus callosum to allow passage of samples.
Has anyone experienced similar difficulties? I seem to remember a casual
conversation about this being a common shortcoming of any tractography
method, but don't know if it was ever rationalized...
Thanks in advance,
Cherif
