sure. There are white matter parcellation schemes around, but we don't have one at the moment.

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 example. I don't know if this is something that is easily done, though.
Thanks again!
Lars
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?

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, Lars Tjelta Westlye
