Comparing the classification of abundant taxa in the simulated metagenomic dataset for each reference database. Taxonomic distribution for the top ten most abundant taxa in the simulated metagenomic dataset, classified at the Phylum, Family, Genus and Species levels with Kraken2 using six different reference databases. The y-axis denotes the percentage of reads classified at each level. The bars along the x-axis each represent the classification results for each database, split by taxonomy as shown in the keys for each level
