Dear all,
Now I use siena to do longitudinal analysis. I use standard siena pipeline getting bad result, because my data with more neck. So I tried "-R" or "-B" in Bet option. Namely, I type:
(1) siena input1 input2 -B "-B"
(2) siena input1 input2 -B "-R"
These two mehods I got good extracted brain, but different final PBVC for the same subject (for adding "-B", THE PBVC is -0.897%; for "-R" is -1.317%).
I don't know how to judge which method is better? If just see the results images, they are so similar.
Anyone can give some advice?
Thanks in advance!
