Thank you for your quick response.
So I have concatenated all my single subject images into a 4D NIFTI image and ran them through Melodic using single-session. Now I have my components, but I am stuck on how to get my group differences. Any suggestions?
Hi - yes this should be possible. If you have "time series" data for each subject then you should use group-ICA and dual-regression; if you only have a single summary image per subject then you should concatenate all images into a 4D NIFTI image and run "single-session"
(default) melodic.

Dear FSL,
I have a FDG PET study that contains 79 subjects that are either FH+ or FH-. The data has already been preprocessed and registered into standard space. I am now wanting to do an ICA analysis to get the components and then do group comparisons with these
components. Is this possible and if so, how do I go about setting this analysis up.
Thank you,
Crystal
