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?
Thank you,

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 lin
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.

Dear Bruce,
My questions is just to learn and to improve my understanding.
The commands recon-all and dt-recon are routinely generating the statistics at
the end of there running and we can check the results in aseg.stats (the
output of recon-all) and fa.stats (the output of dt-recon for FA).

you will need to run mri_annotation2label and specify the output to be
an annotation file instead of a segmentation. Then you will have to run
mri_aparc2aseg, specifying your lobes annotation as well as --labelwm
(look in the recon-all.log file for an example of how wmparc.mgz is
created). Then

For GM area and volume, you can use mris_anatomical_stats. See the
recent thread on how. For the WM volume, how would you define the WM
volume that corresponds to you label? We have a routine that parcellates
WM based on closest proximity to a cortical label.
