**Obtaining gene annotations in refFlat format**

This tool requires gene annotations in refFlat_ format. These data can be obtained from UCSC table browser directly through Galaxy by following these steps:

   1. Click on **Get Data** in the upper part of left pane of Galaxy interface
   2. Click on **UCSC Main** link
   3. Set your genome and dataset of interest. It **must** be the same genome build against which you have mapped the reads contained in the BAM file you are analyzing
   4. In the **output format** field choose **selected fields from primary and related tables**
   5. Click **get output** button
   6. In the first table presented at the top of the page select (using checkboxes) first 11 fields:
      name
      chrom
      strand
      txStart
      txEnd
      cdsStart
      cdsEnd
      exonCount
      exonStarts
      exonEnds
      proteinId
   7. Click **done with selection**
   8. Click **Send query to Galaxy**
   9. A new dataset will appear in the current Galaxy history
   10. Use this dataset as the input for **Gene annotations in refFlat form** dropdown of this tool

@description@

   REF_FLAT=File                 Gene annotations in refFlat form.  Format described here:
                                 https://genome.ucsc.edu/FAQ/FAQformat.html#format9  Required.

   RIBOSOMAL_INTERVALS=File      Location of rRNA sequences in genome, in interval_list format.  If not specified no bases
                                 will be identified as being ribosomal. Format described here:
                                 https://samtools.github.io/htsjdk/javadoc/htsjdk/htsjdk/samtools/util/IntervalList.html and can be
                                 generated from BED datasetes using Galaxy's wrapper for picard_BedToIntervalList tool

   STRAND_SPECIFICITY=StrandSpecificity
   STRAND=StrandSpecificity      For strand-specific library prep. For unpaired reads, use FIRST_READ_TRANSCRIPTION_STRAND
                                 if the reads are expected to be on the transcription strand.  Required. Possible values:
                                 {NONE, FIRST_READ_TRANSCRIPTION_STRAND, SECOND_READ_TRANSCRIPTION_STRAND}

   MINIMUM_LENGTH=Integer        When calculating coverage based values (e.g. CV of coverage) only use transcripts of this
                                 length or greater.  Default value: 500.

   IGNORE_SEQUENCE=String        If a read maps to a sequence specified with this option, all the bases in the read are
                                 counted as ignored bases.

   RRNA_FRAGMENT_PERCENTAGE=Double
                                 This percentage of the length of a fragment must overlap one of the ribosomal intervals
                                 for a read or read pair by this must in order to be considered rRNA.  Default value: 0.8.

   METRIC_ACCUMULATION_LEVEL=MetricAccumulationLevel
   LEVEL=MetricAccumulationLevel The level(s) at which to accumulate metrics.    Possible values: {ALL_READS, SAMPLE,
                                 LIBRARY, READ_GROUP} This option may be specified 0 or more times.

   ASSUME_SORTED=Boolean
   AS=Boolean                    If true (default), then the sort order in the header file will be ignored.  Default
                                 value: true. Possible values: {true, false}
