[Icatb-discuss] Parallel ICA sorting components

[Valsasina P. <val...@hs...>]

Dear all

I am running a parallel ICA analysis using resting state fMRI maps (centrality maps) and sMRI (grey matter) maps from two groups (controls and patients). I selected 13 components for fMRI and 23 for sMRI because these were the numbers estimated by PCA

When looking at produced components, there are basically three possibility: 1) no sorting; 2) sorting by correlation between fMRI and sMRI modalities; 3) sorting by  two-sample t test significance between groups

However, it would be interesting to test if correlation between sMRI and fMRI components is different between the two groups. How can I look at this?
Any suggestion is appreciated

Best regards and many thanks

Paola
