Dear list,
I am about to do MELODIC denoising of an event related fMRi paradigm.
So far, I've run single-session ICAs on all subjects along with the
respective design.mat and .con of the functional paradigm. In some
subjects, I see components that are clearly artefacts (slice dropouts
or classical "motion rims"), but which are correlated with regressors
of interest (indicated by a significant z-score). Now - should I
remove them? Should they stay? Is there any established algorithm or
rule-of-thumb on that?
Thanks and best regards,
Cornelius
