I ran thalamic nuclei segmentation tool using the "freesurfer-darwin-OSX-ElCapitan-dev-20180919-4c582fa" version. The segmented thalamic nuclei were visualized well by FreeView and were able to find most nuclei. But there is no reticular nucleus (R). I also checked the existence of the reticular nucleus with the following matlab code, but it did not exist.

y = MRIread('ThalamicNuclei.v10.T1.FSvoxelSpace.mgz');

find(y.vol == 8125)

Is there any way to find the reticular nucleus?

Best regards,
