**What it does**

De-interlaces a single fastq dataset representing paired-end run into two fastq datasets containing only the first or second mate read. Reads without mate are saved in separate output files.

Sequence identifiers for paired-end reads must follow the /1 and /2 convention.

-----

**Input**

A multiple-fastq file containing paired-end reads, for example::

    @1539:931/1
    ACTTCCCGCGCGTGAAGGCGCCGGCAAACGAGGCTCGGGAAGGGGCTCCCG
    +1539:931/1
    BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
    @1539:931/2

    +1539:931/2
    WNUUZ\P^`BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB

-----

**Output**

Multi-fastq file with left-hand mate only::

    @1539:931/1
    ACTTCCCGCGCGTGAAGGCGCCGGCAAACGAGGCTCGGGAAGGGGCTCCCG
    +1539:931/1
    BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB

Multi-fastq file with right-hand mate only::
