Hi Jen,
Doug is out of town at the fBIRN meeting, and he's the one that will answer this so you might have to wait a bit.

I posted the below question regarding white matter volumes to the list last Friday. I think it fell through the cracks because I sent it out in the late afternoon, and was hoping someone could help me understand 1) the outputs of indicvidual wmparc.stats files and 2) how to tabulate these data like we can with gray matter volumes. Thanks again.

Hi Freesurfer Users,
This may be a newbie question. I am trying to evaluate regional volumes. I have been able to tabulate the gray matter volumes, but cannot figure out how to tabulate all the white matter volumes. I see that in individual folders, there is a file called wmparc.stats. Do any of the tools query this file, or will I need to pull the data manually? Inside this file, I see some of the regions listed as wm-?h-<regionname>. Next to these are sometimes a lot of zeros and sometimes a bunch of values. I am wondering why so many of these do not have values associated with them. I am also wondering why only some of the regions listed in this file are labeled wm, when the file suggests it contains white matter stats...
If there is somewhere on the site that explains white matter volumetric analyses, could someone please send me the link?
Thank you
Jennifer Bramen
