**What it does**

This tool runs the ``samtools bam2fq`` command in the SAMtools toolkit.

By default this will pre-sort your SAM/BAM file by read name and split your
reads into an interlaced FASTQ file for paired reads, and a separate FASTQ
file for singleton reads. A naive conversion is also offered which gives a
single FASTQ file with the reads ordered as in the input SAM/BAM file.

It is quite common to wish to remap high-throughput sequencing data. If you
only have the mapped reads in SAM/BAM format, this tool can "unmap" them to
recover FASTQ format reads to input into an alternative mapping tool.

BAM files can hold both aligned reads and unaligned reads, so another example
usage would be to filter your BAM file to get only the unaligned reads, and
turn those back in FASTQ using this tool ready for *de novo* assembly, or to
try mapping against another reference sequence.
