2D PCA and dendrograms for real datasets. Abundance estimation data for each tool is viewed as a vector, with components being abundance estimations for each organism. The data was transformed using PCA, and the two most significant components were plotted. Hierarchical clustering was also performed on initial vectors. The Figure displays 2D PCA plots and hierarchical clustering dendrograms for all real datasets. Data for MEGAN-N is unavailable on all datasets due to dataset sizes. Data for MEGAN-P is unavailable on datasets SRR15489009 and SRR15489017
