Hi
Although ICA itself is relatively immune to outside noise (motion, cardiac etc), is this still an issue at the 2nd Glm stage of dual regression?
My pipeline uses retroicor (the afni implementation) prior to ICA so card/resp noise is as cleanly removed as I can, but at the second Glm stage, is it advisable to add motion regs for each subject as it becomes (in my head) a quasi-functional connectivity analysis on the individual resting datasets?
All the best,
Jonathan
