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
volume correction as opposed to counting voxels, which we have found to be
more accurate and repeatable.

Hi Bruce,
Kindly I want to inquire about the difference between white matter volume
generated by freesurfer ( specifically the white matter parcellations volume
mentioned in wmparc.stats) and the vwhite matter volume generated by other
tools like fslstats.
For example:
If I use a binarized mask from wmparc.mgz for the precentral gyrus in the
command : fslstats -i MPRAGE.nii.gz ( reoriented and skull stripped) -k
<Precentral gyrus mask> -V
Then
What is the differecne between this volume generated by "fslstats" and the
precenral gyrus volume mentioned in wmparc.stats. Which one is more
accurate?
Bests,
