<!--
    important quote (https://groups.google.com/forum/#!topic/rna-star/q4zGzlPgwXY):
    Hi Gary,

    if you generate the genome with GTF file, and do not specify the value for  - -sjdbOverhang, it will be set to the default 100.
    If you want to be able to set arbitrary value of  - -sjdbOverhang on the fly, you have to generate the genome without annotations (GTF) - then you supply both the  - -sjdbOverhang and GTF file at the mapping step.

    Cheers
    Alex

**What it does**

STAR is an ultrafast universal RNA-seq aligner.

**Extra SAM attributes**

The Standard option includes the following four attributes::

  NH: Number of reported alignments that contain the query in the current record.
  HI: Query hit index, indicating the alignment record is the i-th one stored in SAM
  AS: Local alignment score (paired for paired-end reads)
  nM: Number of mismatches per (paired) alignment

The All option includes the Standard attributes, plus the following four::

  NM: Edit distance to the reference, including ambiguous bases but excluding clipping
  MD: String for mismatching positions
  jM: Intron motifs for all junctions
  jI: Start and end of introns for all junctions

**STAR-Fusion**

STAR-Fusion_ is used to identify candidate fusion transcripts. The recommended_ parameters for running
STAR prior to STAR-Fusion can be pre-selected.

Minor tweaks to output names to suit our downstream purposes, toolshed automated dependencies
and odds and ends of other code and documentation comprising this tool was
