Hi Peter,
recon-all produces an estimate of ICV. In aseg.stats there is a line that looks like:
# Measure EstimatedTotalIntraCranialVol, eTIV, Estimated Total Intracranial Volume, 1696008.240403, mm^3
You can read more about how it is computed at https://surfer.nmr.mgh.harvard.edu/fswiki/eTIV

Hi fellow freesurfers!
I am a Masters student currently working with diffusion images.
I would like to ask you experts how I can obtain ICV from my T1/T2 or diffusion images.
Is there a certain output from recon-all that produces intracranial volume? Or is there a different command I must use?
Thank you all so much for your time. I look forward to hearing from you.
Peter
