Hi Dr Greve,
I tried to follow this web page
https://surfer.nmr.mgh.harvard.edu/fswiki/PairedAnalysis
This tutorial seems to be for cortical thickness data. After sampling each
individual's surface onto the average surface, how can I modify this command to
fit PET data
mris_preproc --target fsaverage --hemi lh \
--meas thickness --out lh.paired-diff.thickness.mgh \
--fsgd pairs.fsgd --paired-diff
Thanks for any help!
John
