In order to investigate the effects of age range, motion exclusion threshold and sample size on functional connectiivity reliability we split the data into two matched samples. For the reliability analysis we averaged all participants in each sample and then calculated how well aligned the two groups were in terms of each pairwise regional connectivity measure. For the out-of-sample prediction analysis we used one half of the data to train a model and then tested it on the other half.
