Dear Pruthvi
In the simplest case, you could just enter the images reflecting a particular component in the differnt time-series into a, in your case, paired, t-test.
This would compare the strength of contribution of this component pre-post treatment for each voxel.
Usually you would interpret significant differences in the sense that this voxel is less/more coupled with the rest of the network reflected by the respective component.

Betreff: [SPM] ICA Subject comparison
Hi everyone,
I have 2 groups(treated and untreated) of resting state data with 2 subjects in each group.I have pre-processed the data using SPM and then I have performed the Independent component analysis(ICA) using GIFT toolbox(http://mialab.mrn.org/software/gift/index.html ).I would like to compare the independent components in treated and untreated, that is, I want to know the changes that have occurred after treatment.Can anyone please help me how to compare?
Thank you
best regards
Pruthvi
