[Freesurfer] Intracranial Volume after Hypothalamus Segmentation

External Email - Use Caution

Dear FreeSurfer Experts,

I am running my subjects through autorecon-1 and then the mri_segment_hypothalamic_subunits function to obtain the divisions of the hypothalamus. However, I just wanted to confirm whether the results are already corrected for intracranial volume during autorecon-1 or within the hypothalamic segmentation (as I assume they would be if I were to run obtain the aseg segmentation further along the pipeline?). Or do I need to calculate eTIV separately?

If so, how do you recommend going about this? Perhaps running something like mri_segstats --subject subjid --etiv-only?

Any help is appreciated. Thank you, Asmin
