Hello,
I am trying to extract the white matter volume based off the aseg.stats. I
noticed the text includes "total cortical white matter volume" and I was
wondering if that is the same as overall white matter volume in the brain?

You will need to create an annotation with your label in it. This might
be tricky to do depending on what you want. The easy way is to run
mris_label2annot with only your label, then run mri_aparc2aseg to
generate something like the wmparc.mgz (look in the recon-all.log file
for the command
Hi Josue
how would you define the borders of the white matter of the gyrus? I guess
you could use the wmparc stuff and just count voxels based on a distance
constraint

Hi John
I'm actually not sure how fslstats works. I'll cc MJ so he can answer that
part of it. When we measure volume (e.g. in the stats files) we do partial

more accurate and repeatable.
