Table 2.
p-Values of the most significant joint source, obtained from two-sample t-tests performed on the columns of the mixing coefficients generated by jICA (first columns), and ICA (last three columns). First and second rows show the results without and with spatial smoothing of the features. GM: gray matter; WM: white matter; DF: deformation field, each used as input features in data fusion analysis. The p-values displayed in the first column passed a Bonferroni correction for multiple comparison (p < 0.00625).
