<!--
    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.

**Compatibility Notes**

STAR has a huge amount of options to filter alignments and to configure the
exact format of its output.

Some tools you may plan to use in your downstream analysis of the results are known to be sensitive to these settings or combinations of them.

*STAR-Fusion*

STAR-Fusion_ can use the chimeric junctions output of STAR as input, but you
need to enable **chimeric alignment detection** by STAR for that dataset to be
generated. Hence, be sure to select:

**Report chimeric alignments?**: `As separate tabular "Junctions" output (Junctions)`.

In addition, for best results it is recommended_ that you

- use **2-pass mapping** for more sensitive novel splice junction discovery

- under *BAM output format specification*,
  **Read alignment tags to include in the BAM output**: select `XS` as an
  additional tag to generate (this is the equivalent of using
  `--outSAMstrandField intronMotif` on the command line)

- under *Algorithmic settings*, **Configure seed, alignment and limits options**:
  `use parameters suggested for STAR-Fusion`.

*Arriba*

Arriba_ can use the BAM with chimeric junctions or both files separately, generated by STAR, as input, but you
need to enable **chimeric alignment detection** by STAR for those datasets to be
generated. Hence, be sure to select either:

**Report chimeric alignments?**: `As separate tabular "Junctions" output (Junctions)` or **Report chimeric alignments?**: `Within the BAM output (together with regular alignments; WithinBAM)`.

In addition, the following parameters_ related to chimeric alignment are recommended for improved sensitivity

- under *Output filter criteria*,
  **Would you like to set additional output filters?**: select `Yes` to set 
  **Maximum number of alignments to output a read's alignment results, plus 1** to 50 

- under *Algorithmic settings*, **Configure seed, alignment and limits options**:
  `use parameters suggested for Arriba`.

*Cufflinks*

.. class:: infomark

   Cufflinks is not considered to be the best tool for use downstream of STAR
   anymore. Consider using *Stringtie* instead, which also should pose no
   compatibility issues.

To avoid compatibility issues with Cufflinks you should:

- select **XS** as a *Read alignment tag to include in the BAM output* if (and
  only if) your sequenced reads come from an unstranded library prep
- *not* select the *jM* and *jI* tags for inclusion
- keep the **HI** tag selected and
- select *HI tag values should be* **zero-based**
- exclude **All alignments across non-canonical junctions** under *Output
  filter criteria -> Exclude the following records from the BAM output*
