Hi, i am also looking for a option to evaluate resting data and the strength of network-Correlation (individually or between groups). I have already analyzed my data with Concat-ICA in Melodic, would like to test your beta-test script.

Betreff: Re: [FSL] Strength of correlation
Hi,
For activation-related experiments, I suggest you see Jill's PPI page
http://www.fmrib.ox.ac.uk/Members/joreilly
For resting FMRI, we recommend using Concat-ICA (this is an option in
the MELODIC GUI) followed by dual regression to compare resting
networks across subjects - if you'd like to test out our beta-test
script for this, let us know.
Cheers.
