Sorry, I mean I was guessing the cause of the inconsistency Farzad pointed
out.
So he was asking that after statistical threshold masking, the remaining
significant results should show the same blob patterns compared with
unmasking results, but actually when the mask was applied the survived
blobs look different. Why is this?
