Hi Dhinakaran,
4 and 5 aren't part of our current automated segmentation. Sorry, I'm not sure how visible they are in a 1mm T1-weighted image

Dear all,
Hope your research is going smoothly.
My question refers to the basal ganglai components. I previously shot an email which Prof. Fischl was kind enough to reply to: the basal ganglia is not computed as a structure of its own in FreeSurfer.
These are the structures of the basal ganglia one can gather:
(1) striatum (Caudate and putament)
(2) Ventral Striatum - (a) nucleus accumbens (b) most ventral aspects of caudate and putament
(3) Celobus pallidus (internal and external sectors)
(4) Substancia Nigra
(5) Subthalamic nucleus
Here are my questions:
=> Structures (1), (2), (3) and (4) can be found... however, am having trouble locating the segmentation label number for the subthalamic nucleus.
=> The output for (4) is not reported in asegstats2table (while other structures are). Any other suggestions to extract the volume out?
Thanks, Dhinakaran.
