Evaluation of GO term enrichment in the results of the clustering methods. a The total numbers (sum) of GO terms detected as significantly enriched in the results of each of the eight methods across the 20 selected datasets. b Numbers of terms detected as significantly enriched in the same dataset by x or more methods; over the 20 datasets, 7404 terms were detected by at least one method, 2873 (39%) of which are exclusive to a single method, and only 503 (7%) terms were unanimously agreed by all eight methods. c The distribution of the 503 unanimously agreed GO terms over the 20 datasets. d Pairwise comparisons of the p values of the unanimously agreed GO terms in the clusters returned by clust with each of the other clustering methods. Green squares indicate that the p values for the GO terms returned by clust were better than those of the comparative method (Wilcoxon test p value ≤ 0.01), blue squares indicate the opposite result (Wilcoxon p value ≥ 0.99), and white squares indicate that there was no significant difference (0.01 < p < 0.99). The values to the right side of this matrix are the resultant p values when the Wilcoxon test is applied to the full dataset of all 503 unanimously agreed GO terms
