Figure 4From: Discovering functional linkages and uncharacterized cellular pathways using phylogenetic profile comparisons: a comprehensive assessmentResults from the t-tests measuring the statistical significance of the difference in the means of the distributions of mutual information scores of random protein pairs and protein pairs with pathway similarity ≥ 50%. The t-scores for all 16 reference sets of genomes are statistically significant for both the E. coli and the yeast proteins.Back to article page
