Twin identification success rate using the global FCF or ECF based on different measures.

	FC profile pooled across bands
FC	original	SVD
AEC	35.9%***	53.1%***
AEC-c	23.4%***	37.5%***
PLI	3.1%	9.4%**
dPTE	57.8%***	76.6%***

For every subject the global FCF or ECF was obtained combining the subject’s FCF or ECF computed for the individual frequency band. The success rate for every FC and EC connectivity measure is reported: Amplitude Envelope Correlation without (AEC) and with correction (AEC-c), directed Phase Transfer Entropy (dPTE) and Phase Lag Index (PLI). Success rate based on the original data, as well as after removal of the common pattern across subjects (using SVD), are given. The asterisks represent the significant values after permutation testing: p-value ≤ 0.05(*), p-value ≤ 0.01(**) and p-value ≤ 0.001(***).
