I have attached a screenshot of one of the slices. from what I see it is going a little far in the medial and lateral parts. I am using a 3TC image taken by Philips device. Is there any way to limit the region of interest before running the recon-all to only segment the thalamus and may give better results?

Thank you

Hi Dorsa

why do you think it  is going out too far? What intensity volume are you
overlaying it on? Many segmentations miss the lateral parts of the
thalamus since they have so much myelin in them
