Information flow in a GRN. x_i(t) denotes the gene expression of the ith gene. Since the gene regulation is directional, the graph of the GRN is a directed graph (digraph). The signal processing model of the GRN is given in Equation (26) by microarray temporal data; the signal flow between any two genes is described by Equation (28) and the information transductivity can be obtained by solving Equation (30). If data are available from only one temporal sample microarray, the static state-space model in Equation (32) is used, and the information flow between any two genes is given by Equation (34), with information transductivity in Equation (36).
