Before revision:  Rev.~E 92} , 052815 (2015) ), we introduce a family of q-dependent minimum spanning trees (qMST) that are selective to cross-correlations between different fluctuation amplitudes and different time scales of multivariate data .
After revision:  Rev.~E 92} , we generalize the concept of minimum spanning tree (MST) by introducing a family of q-dependent minimum spanning trees (qMST) that are selective to cross-correlations between different fluctuation amplitudes and different time scales of multivariate data .
