**What it does**

Simple interface to manipulate BAM files through the use of SAMtools.

View the original SAMtools documentation: http://samtools.sourceforge.net/

------

**Usage**

**Merge BAM files**: Merges 2 or 3 input BAM files into a single BAM file.

**Split BAM file**: Randomly split input BAM file into 2 BAM files. 

**Filter BAM file**: Removes aligned reads from input BAM files with mapping quality lower than entered Minimum Mapping Quality (MMQ) value.  

**Calculate coverage QC**: Calculates QC metrics such as percentage of genome covered and average coverage of bases covered for the input BAM and reference files.
