actually, Doug's wm parcellation tool should be able to parcel out the
frontal white matter from a lobar segmentation.

That will not be able to separate the only frontal WM from the rest of
the WM, isn't it? I have used FSL (a mix of bet,flirt and fnirt) with
an atlas of the lobes (that covers WM and GM) for that kind of job

You can get the WM from our white matter segmentation (wmparc.mgz and
stats table wmparc.stats). You'd need to pick the cortical labels that
you want to define as the "frontal lobes". You should create a binary
mask with mri_binarize, passing the indices of the segments you want to
use with the --match option, then load the mask in tkmedit to see
whether it is what you expect. You can do a similar thing with the gray
matter, but you can get the volumes from the ?h.aparc.astats

Hi freesurfer gurus,
We are doing some freesurfer processing for a collaborating lab and the
PI has asked us for a measure of gray matter volume and a measure of
white matter volume, both of which need to be specific to just the
frontal lobes. Does anyone know of a simple, and accurate, way of
acquiring these measures from freesurfer?
Thanks.
Jared
