Figure 5

Expression matrices of two gene sets (upper panel) are transformed into Renyi relative entropy matrices by all sample pair-wise comparisons (middle panel). For each condition, Interaction Score (IS), a kind of correlation coefficients, between a pair of entropy matrices is obtained. Upper diagonal heat maps in the middle panel are transformed into scatter plots in the lower panel where ISs are depicted as fitted lines. (Modified from [12]).
