Algorithm 1: The RICI algorithm used to estimate the time-varying FC.

1:
foreach time sampledo
2:
Set the minimal window size
3:
while $R \geq R_{c}$ do
4:
Compute confidence interval (CI) for a given window
5:
Estimate lower and upper confidence interval boundaries $D_{u}$ and $D_{l}$
6:
Update $D_{u_{M I N}}$ and $D_{l_{M A X}}$
7:
Compute new criterion ratio R
8:
end
9:
Compute functional connectivity for the given window
