Figure 1From: Factor analysis for gene regulatory networks and transcription factor activity profilesFactor loadings matrix of the E. coli network. (a) connectivity matrix of E. coli as suggested by Kao et al. [6] (a black entry corresponds to a non interaction while a white entry corresponds to an interaction), (b) distribution of the number of genes regulated by each TF, and (c) distribution of the number of TFs regulating each gene in the E. coli network of (a).Back to article page
