**What it does**

This tool runs the ``samtools stats`` command. It has the following options::

    -c, --coverage <int>,<int>,<int>    Coverage distribution min,max,step [1,1000,1]
    -d, --remove-dups                   Exclude from statistics reads marked as duplicates
    -f, --required-flag  <str|int>      Required flag, 0 for unset. See also `samtools flags` [0]
    -F, --filtering-flag <str|int>      Filtering flag, 0 for unset. See also `samtools flags` [0]
        --GC-depth <float>              the size of GC-depth bins (decreasing bin size increases memory requirement) [2e4]
    -h, --help                          This help message
    -i, --insert-size <int>             Maximum insert size [8000]
    -I, --id <string>                   Include only listed read group or sample name
    -l, --read-length <int>             Include in the statistics only reads with the given read length []
    -m, --most-inserts <float>          Report only the main part of inserts [0.99]
    -q, --trim-quality <int>            The BWA trimming parameter [0]
    -r, --ref-seq <file>                Reference sequence (required for GC-depth and mismatches-per-cycle calculation). Galaxy
                                        will provide options for selecting a reference cached as this Galaxy instance or choosing
                                        one from history.
