probably not, as the aseg.stats calculation uses partial volume estimates.

Hey Doug, THanks. That looks simpler. I'll probably use that.

Question: Will the total volume of a ROI taken from aseg.mgz correspond to
the volume given in aseg.stats?

      If you have matlab, you can load the aseg into matlab, like
      aseg = MRIread('aseg.mgz');
      vol = length(aseg.vol(:,:,n:256) == ID);
      where ID is the code number for the ROI you want  as found in

Hi All,

I would like to determine the volumes of a segmented region
below or above an arbitrary line in one of the planes. For
example, what would be the remaining volume of a label when z >=
nth slice, where I would have previously determined the
appropriate value of n.



Thanks,
Josh
