To ensure that our choice of particular preprocessing stream did not drive the findings, preprocessing was repeated with other options: (i) slice-timing correction, (ii) partialing of the square, autocorrelation, and 1st derivative of motion parameters, (iii) partialing the 1st derivative of global, ventricular, and white matter signals, (iv) determination on a participant-specific basis whether partialling of global signal was necessary (via the Global Negative Index), (v) motion scrubbing. Connectivity matrices remained extremely similar (correlations > .97), indicating that findings were not specific to our preprocessing stream.
