Figure 3. Impact of low abundance human and PhiX174 sequence contaminations on the correlation between expected taxonomic and k-mer-based beta-diversity metric. (A) Distribution of the percentage of human reads content in the simulated dataset; (B) Spearman correlations between the expected taxonomic and k-mer-based Bray-Curtis distance for the human contaminated dataset; (C) Distribution of the percentage of PhiX174 reads content in the simulated dataset; (D) Spearman correlations between the expected taxonomic and k-mer-based Bray-Curtis distance for the PhiX174 contaminated dataset.
