Thank you Bruce and Moo Chung
I will try with those tools
I have another question:
If I want to use GRFT on smooth thickness spms over
the fsaverage subject , should I use the fsaverage
white matter total surface area which is 70394.7 mm2
or the group average surface area which is 86444.7
mm2?
I
sounds reasonable to me, but we should call it something else (normalized
FI/CI?)

Hi Graham -
First off, your observation that the FI seems correlated with area is
completely correct. I'm not sure if you have the FS source code? Anyway,
looking at t
Hi Jorge,
You can make your own fsaverage. In the QDEC wiki page you can find a quick
howto.

Hi Cameron,
I want to run a classification analysis on my functional data from
all of the cortex using matlab. It is not something complicated but
the very fist step is to run a PCA on all the data from all the
voxels in the cortex. I am trying to reduce my data set as much as I
can as th

Yes, dividing out area does look like a first step, justified by the way
the per-vertex values are calculated. This gives the result units of mm^-2,
which maybe has an interpretation something alon
Hi Maryam,
not sure if Doug is still reading email, but he would be the one to ask.
I think you should be able to use mri_vol2surf to sample a volume
timeseries into an NxT (nvertices x timepoints) "volume" in .mgz format.
You could then read the surfaces into matlab, and the indices into the
