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; (C) Absolute differences between the exact k-mer presence/absence Jaccard distances and distances after low abundance k-mer filter; (D) Spearman correlation between the expected taxonomic presence/absence Jaccard index and the k-mer-based Jaccard index when increasing the low abundance k-mer filter.
