so you see huge loss of gm volume, but not of thickness? What happens to
the surface area? And what does "huge" mean in this context? What kind of
#s are you seeing, and what kind of means and stds to you see in your
controls?

Thanks for the answer, Bruce.
My aim is to assess severity of cortical atrophy and I am trying to find
optimal SINGLE parameter for that, i.e. GM thickness, GM volume, or something
else.
What I do is, I take mean thickness of a parcel A of a GM from ?h.aparc.stats

Hi Martin,
when you look at the mean difference between this subject and controls
you mean it's within a std of the controls? That's not terribly
surprising, as there is a lot of normal neuroanatomical variability. Is
it below the mean over much of the cortex? Is the overall mean thickness

Hi,
We have a problem with the Talairach transformations. When we load the
talairach.mgz file using tkmedit the axial and coronal orientations are
swapped and displaced in the window.
The puzzling thing is that if we use tkregister2, the registration is
very good. Any idea of why?
I found a

Hi folks,
I have been puzzled for a while with the results from couple of my subjects.
They all have clearly visible cerebral atrophy (says neuroradiologist). I ran
them through FS-4.0.1 and aseg.stat gives me, as expected, severe loss of
gray matter (and others as well) as follows:
