ICA networks
Dear CONN community and Alfonso,
I have a question regarding ICA analysis in CONN, more precisely how I can see which regions the components consist of. I first looked at the networks (which regions they consist of) by selecting 'all subjects' in the spatial section of the ICA networks second-level analysis, with the contrast [1]. In the results explorer I then changed the voxel-wise threshold for each network in order to obtain a nice and clear network.
However, when looking at the components across all subjects in the 'summary' section, for some networks I see very different (or at least much less) clusters for the same components.
How is this possible? What is the difference between these 2 sections? And which one should I use in order to identify the networks I'm interested in?
Any help would be greatly appreciated!
Best whishes,
Julia
