Fig. 1: The flowchart of the FNC analysis to investigate cross-scan FNC.

a, Neuromark framework extracts robust functional components from the ABCD data. Component templates are identified using two independent data with different repetition time (TR). b, FNC is estimated using the TCs of components from each scan. c, Cross-scan FNC similarity is measured by the correlation between FNC from different scans. d, Individual identification is performed on the basis of the cross-scan FNC similarity. e, Association analysis between FNC stability (intra-participant FNC similarity) and individuals’ behaviour via the LMM.
