Dear FSL experts,
I have the z-transformed maps of RSFC for two seeds (for any subjects) and
I would like to test the correlation between the two using randomise,
including the correlation per group interaction (cases vs controls).
How can I do this?
Is it right to use the maps of the first seed as the input file and the
maps of the second seed as an EV?
To test for interaction, perhaps I have to build two merged files of maps
(one with 0s in controls and the other with 0s in cases) and demeaned
across groups. Is it right?
Do I have to use the -d demean option in randomise, too?
Thank you for any help
Best,
Angela
