Fig. 3From: Robust structure measures of metabolic networks that predict prokaryotic optimal growth temperatureRobust measures on directed graphs: a Pearson’s correlation between the node normalised size of the largest strongly connected component and the optimal growth temperature; and b Pearson’s correlation between the node normalised hierarchy flow and the optimal growth temperature. These measures were applied to directed substrate graphs for all 228 species, without ubiquitous metabolitesBack to article page
