Hi Rudolph,
I was wondering if you could give me any hint regarding how to use an apriori GM segmentation in freesurfer. I basically already have a good segmentation of GM vs WM and CSF from spm and would like to use this towards the computing cortical thickness.
Thanks, Elisa

Hi Elisa,
Rudolph Pienaar (ccd) put together something for this I think.
cheers Bruce

Hi all,
I have a question regarding cortical thickness estimation in freesurfer. I was wondering whether it is possible to input in freesurfer the gray matter segmentation as an a priori. Specifically, I run freesurfer on a set of cases on which I previously run spm and obtained a good discrimination between GM, WM and CSF. I would like to use these segmentation instead to proceed with manual edits on freesurfer segmentation output for gray matter segmentation, that sometimes was not segmented correctly. Would this be possible?
Thanks a lot, Elisa
