FreeSurfer Subcortical Segmentation
FreeSurfer now automatically runs automated labeling of the brain volume and this is included in all versions of the September 2005 release. In subcortical segmentation, each voxel in the normalized brain volume is assigned one of about 40 labels, including:
- Cerebral White Matter, Cerebral Cortex, Lateral Ventricle, Inferior Lateral Ventricle, Cerebellum White Matter, Cerebellum Cortex, Thalamus, Caudate, Putamen, Pallidum, Hippocampus, Amygdala, Lesion, Accumbens area, Vessel, Central Diencephalon, Third Ventricle, Fourth Ventricle, Brain Stem, Cerebrospinal Fluid
However, if you processed your anatomical data using previous versions, you can just run the subcortical segmentation separately if you wish to obtain the automated labels. The September 2005 release of FreeSurfer by default uses the automatically segmented brain volume (ASEG) to segment the white matter volume (WM). If you wish for whatever reason to recreate the final surfaces, you must use the -noedit_wm_with_aseg flag so that it uses the white matter volume (WM) that you edited.
