Thanks for the response. If I want to compare to see if there's significant difference between the two groups for some of the IC components, how would I be able to do that? To get outputs like these for each component: dr_stage2_ic0001.nii.gz dr_stage3_ic0001_tstat1.nii.gz
dr_stage3_ic0001_tfce_p_tstat1.nii.gz
dr_stage3_ic0001_tfce_corrp_tstat1.nii.gz

Hi - one set of images are zstat versions of the output (dividing the 'effect size' by the residuals) and the other set are the 'effect size' (like PE inFEAT).
Cheers.

Hello,

I'm fairly new to using dual regression. I ran dual regression on my two sets of model-free data each with 3 subjects using concat ICA to compare the 2 groups (6 inputs total). The ICA result showed 33 components, but when I ran dual regression, I got outputs like this:
dr_stage2_subject00005_Z
dr_stage2_subject00005
dr_stage2_subject00004_Z
dr_stage2_subject00004
dr_stage2_subject00003_Z
dr_stage2_subject00003
dr_stage2_subject00002_Z
dr_stage2_subject00002
dr_stage2_subject00001_Z
dr_stage2_subject00001
dr_stage2_subject00000_Z
dr_stage2_subject00000

This does not look like the dual regression outputs I've seen before. Does anyone know what might have caused this?

Thanks,
Amy
