Thank you, Drs. Fischl and Greve. I was able to compute the surface CNR
following your suggestion.

You can read in the mgh file with MRIread.m
Make sure to account for the fact that the annotation vertices will be
0-based and matlab is 1-based

actually, if you convert the aparc annotations to a bunch of labels, you
can run:
mri_cnr -label ...
and it will limit the calculations to that label. FOr example:
mri_cnr -label ~/links/subjects/bruce.dev//label/lh.cortex.label
~/links/subjects/bruce.dev//label/rh.cortex.label
~/links/sub

Thanks, Dr. Greve. Where can I find the correspondence between the vertices
in ?h.w-g.pct.mgh and the parcellations?

you can get the contrast from surf/?h.w-g.pct.mgh, which you can average
over each parcellation. Not sure where you would get the noise term from.

I apologize, Dr. Fischl, that I wasnt clear.
We are using Desikan-Killany atlas that has 68 surfaces defined on the
atlas, 34 on each hemisphere.
I might be wrong, but I was thinking that there should be a way to define
CNR of orbitofrontal cortex (O
can you clarify what you mean? What 68 surfaces do you mean? And what do
you mean by CNR of a surface?

Hi,
We were interested in measuring CNR of each of the 68 surfaces in
Desikan-Killany atlas and co
