Bivariate coefficients is for bivariate cGCA computation. Multivariate coefficients is for multivariate cGCA computation. The two selection are based on coefficient-based ROI-wise GCA.

ROI_sequence: save the sequence of pair ROI for bivariate GCA. Three pairs of computation have been performed: ROI1 v.s. ROI2; ROI1 v.s. ROI3 and ROI2 v.s. ROI3.Bivariate Results: Order was 1. Left column is the signed-path coefficients (ROI1 v.s. ROI 2,… see ROI_sequence). Right column is the auto regression coefficients.
