ASD vs. TD classification performance: the impact of using different parcellation schemes in the leave-one-site-out cross-validation scheme is shown in terms of mean and standard deviation of AUC. For each atlas, the number of descriptive features (m) is reported.

	Atlas, mean ± std
Classification	AAL	HO	CC	POWER
	(m = 4005)	(m = 5995)	(m = 16836)	(m = 26335)
AUC (%)	72 ± 3	75 ± 5	70 ± 10	64 ± 6

AUC, area under the ROC curve; std, standard deviation; AAL, Automated Anatomical Labeling; HO, Harvard-Oxford; CC, Craddock.
