Hi Dorsa
if you upload your subject I'll take a look. What is a 3TC image? I don't know what contrast the image you sent is but I would be cautious about only using it to assess the accuracy of the T1 segmentation

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

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 cheers Bruce On Wed, 19 Oct 2016, Dorsa Haji Ghaffari wrote: > Hi, > I have done the sub-cortical segmentation in Freesurfer and have extracted the left thalamus, when I put > it on top of the original MRI, it seems like it is getting out of the border of thalamus, also it is not > smooth.
