Before revision:  We show that the qMST graphs can complement \rho_q in detection of "hidden" correlations that cannot be observed by the MST graphs based on \rm DCCA and, therefore, they can be useful in many areas where the multivariate cross-correlations are of interest (e. g. , in portfolio analysis)\ne  .
