Bruce: is this an average weighted on the surface of the cortices or just a pure arithmetic mean? Thanks, Francesca

do you mean the mean across the entire cortex? If so, mris_anatomical_stats will give you that. On Mon, 10 Jul 2006, Stefano Pellegrini wrote:
Hi everybody,
I have a small problem with an old version of freesurfer. I am studing
some data that someone analyzed some months ago using the old version of freesurfer. I am looking for the mean cortical thickness of each
hemisphere,
but I have found only the thickness af each single area of the
segmented
cortex in a txt file in the label directory. Can anybody please tell
me where
I can find the information about the average cortical thickness of
each
hemisphere? Should I recalculate it averaging all the cortical labeled
areas
(each weighted on the extention of its surface)?
thank you,
