**What it does**

Runs the ``mirabait`` utility from MIRA v4.0 to filter your input reads
according to whether or not they contain perfect kmer matches to your
bait file. By default this looks for 31-mers (kmers or *k*-mers where
the fragment length *k* is 31), and only requires a single matching kmer.

The ``mirabait`` utility is useful in many applications and pipelines
outside of using the main MIRA tool for assembly or mapping.

.. class:: warningmark

Note ``mirabait`` cannot be used on protein (amino acid) sequences.

**Example Usage**

To remove over abundant entries like rRNA sequences, run ``mirabait`` with
known rRNA sequences as the bait and select the *negative* matches.

To do targeted assembly by fishing out reads belonging to a gene and just
assemble these, run ``mirabait`` with the gene of interest as the bait and
select the *positive* matches.

To iteratively reconstruct mitochondria you could start by fishing out reads
matching any known mitochondrial sequence, assembly those, and repeat.


**Notes on paired read**

.. class:: warningmark

While MIRA 4.0 is aware of many read naming conventions to identify paired read
partners, this version of the ``mirabait`` tool considers each read in isolation.
Applying it to paired read files may leave you with orphaned reads.

The version of ``mirabait`` included in MIRA 4.9.5 onwards is pair-aware.
