Changes in average in functional connectivity, and variability of connectivity estimates, as a function of parcellation scale.

	aal84	parc91	parc230	parc438	parc890	parc1314	parc4320
Mean functional connectivity	0.56	0.56	0.50	0.45	0.43	0.41	0.35
Between-subject variability	0.09	0.09	0.09	0.08	0.08	0.08	0.08
Within-subject variability	0.17	0.17	0.18	0.19	0.19	0.19	0.21

The mean functional connectivity estimates were obtained by computing the average wavelet correlation coefficient for each subject's unthresholded connectivity matrix, and then taking the sample average of these mean values. Between-subject variability was computed by taking the sample standard deviation of the mean correlation value of each subject's matrix. Within-subject variability was computed by calculating the standard deviation of correlation values in each subject's matrix, and then taking the sample mean of these standard deviation values.
