Thanks, that was really helpful. The ROI's are definitely being created based on the
literature and not by first doing the whole-head analyses.
One additional question that I had was what threshold should I be using for creating such a
mask? I can see the advantage of using a lower threshold such as 5% so that I can account
for inter-subject variations but also can think of using the 25% or the 50% threshold so that
the tract that I am choosing is more representative. Any input on this would be much
appreciated.
Thanks again,
