you'll have to be more specific about what "brain surface contour" means.

Dear Freesurfers,
I need to extract the brain parenchymal fraction to check brain atrophy in my
patients.
The BPF is defined as "the ratio of brain parenchymal tissue volume to the
total volume contained within the brain surface contour".
In the text file aseg.stats, I found this info:
# Measur
It excludes WM in cerebellum and brain stem.

Hi All,
I am using freesurfer 5.1 and I want to compute the brain parenchymal fraction
(GM+WM/GM+WM+ventricularCSF).
In aseg.stats, I get the whole GM vol and I can also get the total ventricular
CSF by adding the vols of different ventricles.
But I am confused abt the terminology - Cortical
