Dear FSL experts,
I ran MELODIC + dual regression to estimate the average
time series of each component for each subject (stage 1
outputs). I want to use these for further analyses. Now
I'm wondering how exactly the individual time series are
estimated. Some of my components contain negative as well
as positive connections. So if the stage 1 outputs are
generated by averaging time series within each component
(as I have read in a few papers), won't this lead to
faulty results if there are positive and negative
connections? I guess that "averaging" might just be wrong
terminology here and the negative connections are somehow
accounted for. Still, I want to make sure because this
might explain some of my results.
Thanks a lot for your help!
Best,
Katharina
