Fig. 5.

Kraken performance on a single dataset containing both bacterial (a) and viral (b) reads. Performance from metagenomic assembly approach is shown on both unfiltered contigs and results filtered by a minimum of 5 contigs required for classification. Kraken performance on raw reads is shown both unfiltered and filtered by a minimum of 100 reads for classification. Bacterial performance is classified at genus level whereas viral performance is regarding species level due to peculiarities in taxonomy
