Fig 6. Taxonomical analysis using the consensus database.

A Representation of predicted species abundance using Metaphlan-II, Clark-S, and Kraken, based on mock community data. B Predicted species abundance representation using full depth of fecal sample (200 million read pairs). C Composition of the 19 predicted species common to all methods, and specific for Metaphlan-II. The bar named Metaphlan_ONLY represents the species predicted by Metaphlan-II alone, whereas the other three bars represent the common species predicted by each method and their respective proportion. Species with abundance proportion below 1% are not shown in the figure. The sum of abundance proportion for each method is shown at the top of each bar. D Species richness for different taxonomy classification approaches at different sequencing depths. Species richness is shown as mean values and 95% confidence intervals (shown as error bars). E Species evenness for different taxonomy classification approaches as dependent on different sequencing depths (error bars depict 95% confidence intervals).
