**What it does**

Kraken2 is a taxonomic sequence classifier that assigns taxonomic labels to short DNA reads. It does this by examining the k-mers within a read and querying a database with those k-mers. This database contains a mapping of every k-mer in Kraken's genomic library to the lowest common ancestor (LCA) in a taxonomic tree of all genomes that contain that k-mer. The set of LCA taxa that correspond to the k-mers in a read are then analyzed to create a single taxonomic label for the read; this label can be any of the nodes in the taxonomic tree. Kraken is designed to be rapid, sensitive, and highly precise.

-----

**Output Format**

Each sequence classified by Kraken results in a single line of output. Output lines contain five tab-delimited fields; from left to right, they are::

    1. "C"/"U": a one letter code indicating that the sequence was either classified or unclassified.
    2. The sequence ID, obtained from the FASTA/FASTQ header.
    3. The taxonomy ID Kraken 2 used to label the sequence; this is 0 if the sequence is unclassified.
    4. The length of the sequence in bp.
    5. A space-delimited list indicating the LCA mapping of each k-mer in the sequence. For example, "562:13 561:4 A:31 0:1 562:3" would indicate that:
            a) the first 13 k-mers mapped to taxonomy ID #562
            b) the next 4 k-mers mapped to taxonomy ID #561
            c) the next 31 k-mers contained an ambiguous nucleotide
            d) the next k-mer was not in the database
            e) the last 3 k-mers mapped to taxonomy ID #562
