Subject: [Freesurfer] Calculation of MRI intensity

        External Email - Use Caution        

Hi Freesurfer Team,

Please I want to calculate the mean intensity of a skullstripped MRI image. I do not want to use recon-all because I do not want to parcellate or segment it. Is there such utility or function in freesurfer?

Thank you.

Sincerely,

Ernest Kissi Kontor.
