Hi Bruce,

Thank you for your response. I just want to draw manually the region of the new label on the images of few subjects.

What I am about to do is to define a new label for the trigeminal nerve sensory nucleus (just roughly as the region that the nerve enters the brainstem); I just need to label it manually for all subjects.

Best,
Emad

Hi Emad

do you mean draw one manually or add it so it is automatically labeled in new subjects? If the latter it requires manually labeling a training set and rebuilding a classifer, etc..., so it is far from trivial

cheers
Bruce
