It is working if I edit the mask manually, but it took a lot of time to edit the mask manually. I ran this process with earlier version of BDP (14a), and it generated correct dwi mask. So I wonder if the wrong dwi mask from the new version of BDP is a kind of an error.
Hello, thank you for your reply. I am trying to identify stroke lesion. So I want to make a label of stroke lesion on each individual, and transform the lesion label to standard atlas space to compare the lesions among different stroke patients.
