**What it does**

This tool uses the samtools view command in SAMTools_ toolkit to filter a SAM or BAM file on the MAPQ (mapping quality), FLAG bits, Read Group, Library, or region.

**Input**

Input is either a SAM or BAM file.

**Output**

The output file will be SAM or BAM (depending on the chosen option), filtered by the selected options.

**Options**

Filtering by read group or library requires headers in the input SAM or BAM file.   

If regions are specified, only alignments overlapping the specified regions will be output.  An alignment may be given multiple times if it is overlapping several regions.  
A region can be presented, for example, in the following format::

  chr2	(the whole chr2)
  chr2:1000000	 (region starting from 1,000,000bp) 
  chr2:1,000,000-2,000,000	(region between 1,000,000 and 2,000,000bp including the end points). 

Note:  The coordinate is 1-based.

Multiple regions may be specified, separated by a space character::

  chr2:1000000-2000000 chr2:1,000,000-2,000,000 chrX
