Hello, i am currently looking at the WM Volume in heat mode and am curious as
to if i need to fill in all the small missing voxels located within the
boundary as well as the bigger holes?
Kind regards, Michael

Dear Freesurfers,
In what file inside the patient_name/stats folder do I find the total white
matter volume?
In the file "aseg.stats" there is something called lh/rh "cortical white matter
volume", is that the right value to look at?
Thank you,

Hi all,
is there a way I can attain the total wm volume for each of the
hemispheres? And is it possible to estimate the wm volume of certain
gross anatomical areas, like the different lobes?
Thanks!
Best wishes,

Freesurfer provides ctx- and wm- volumes on either side of the "white" labelled
sheet, all for a particular cortical region.
What is the idea which is used to limit the extent of the wm- volume which is
adjacent to a particular ctx- volume?
Is it as simple as a maximum distance normal to the whi
nope, as long as the white surface is accurate you should be all set.

Yes, that is the right value. We changed the name of it in more recent
versions to CerebralWhiteMatter

you can get an estimate by loading the filled volume into matlab and
counting the # of 127 (rh) and 255 (lh). Nothing lobar though - what would
it mean? Where would you draw the borders?

Thanks for your swift reply, Bruce!
I don't know how the lobar drawing would be done, but am curious if there
exist any kind of 'predefined regions' that could further refine the
estimates of the total wm volume. It could be interesting to estimate
where the wm loss is most prominent in aging, for
sure. There are white matter parcellation schemes around, but we don't
have one at the moment.

Bruce

the wmparc gets the cortical parcellation of the closest cortical
parcellation (not necessarily normal to the surface). I think it has to
be within 5mm of cortex or else it gets "Unsegmented White Matter". The
method is described here
