Figure 7. Impact of low abundance k-mer filter on the estimation of k-mer-based Bray-Curtis distances. (A) Absolute differences between the exact k-mer Bray-Curtis distances and distances after low abundance k-mer filter; (B) Spearman correlation between the expected taxonomic Bray-Curtis index and the k-mer-based Bray-Curtis index when increasing the low abundance k-mer filter;
