Hi,
I only had a quick look (slow internet connection right now), but
components 1, 2 and 4 look like typical "motion artefact" components
with rim- or halo-like "activations/deactivations". The cerebellar one
(don't remember the number) looks quite good. Some smearing over brain
edges will occur occasionally (due to smoothing?) in tcICA - nothing
to worry too much about in my opinion. Have a look at the z-map in
FSLView with an increased z-threshold (6 usually works quite well) to
get an idea of the core component of your IC map.
Cheers,
Cornelius
