Hi,
It sounds like you want a combination of running "cluster" and
"avwmeants" to extract information from the summary stats and then
original Fa values (from all_FA_skeletonised).
Yes, most of the studies to date have been doing two-group testing -
just google for TBSS and hopefully you'll find some - e.g. the really
nice work by Anjari in NeuroImage, etc.
Cheers.
