Fig. 4From: decOM: similarity-based microbial source tracking of ancient oral samples using k-mer-based methodsMST on a simulated ancient dental calculus metagenome. Bar plots for the source environment proportion estimation obtained after evaluating each method using as sources all the samples from the 360 metagenomic collection, and using as sink a synthetic ancient oral data set. The expected content of this synthetic sample is \(100\%\) oralBack to article page
