-The most useful summary file is the `*kaijutable.txt` file which summarises hits across all reads. However if you wish to look at more precise information on a per-read basis, see the `*tsv` file. The default taxonomic rank is `species`. You can provide a different one by updating the argument `--kaiju_taxon_rank`.
