**What it does**

Runs MIRA v4.0 in de novo mode, collects the output, generates a sorted BAM
file, and then throws away all the temporary files.

MIRA is an open source assembly tool capable of handling sequence data from
a range of platforms (Sanger capillary, Solexa/Illumina, Roche 454, Ion Torrent
and also PacBio).

It is particularly suited to small genomes such as bacteria.


**Notes on paired reads**

.. class:: warningmark

MIRA uses read naming conventions to identify paired read partners
(and does not care about their order in the input files). In most cases,
the Solexa/Illumina setting is fine. For Sanger capillary sequencing,
you may need to rename your reads to match one of the standard conventions
supported by MIRA. For Roche 454 or Ion Torrent the appropriate settings
depend on how the FASTQ file was produced:

* If using Roche's ``sffinfo`` or older versions of ``sff_extract``
  to convert SFF files to FASTQ, your reads will probably have the
  ``---&gt; &lt;---`` orientation and use the ``.f`` and ``.r``
  suffixes (FR naming).

* If using a recent version of ``sff_extract``, then the ``/1`` and ``/2``
  suffixes are used (Solexa/Illumina style naming) and the original
  ``2---&gt; 1---&gt;`` orientation is preserved.

The reason for this is the raw data for Roche 454 and Ion Torrent paired-end
libraries sequences a circularised fragment such that the raw data begins
with the end of the fragment, a linker, then the start of the fragment.
This means both the start and end are sequenced from the same strand, and
have the orientation ``2---&gt; 1---&gt;``. However, in order to use the data
with traditional tools expecting Sanger capillary style ``---&gt; &lt;---``
orientation it was common to reverse complement one of the pair to mimic this.
