**What it does**

PRINSEQ is a tool for easy and rapid quality control and data processing of metagenomic and metatranscriptomic datasets.
This tool allow to process the sequences with filtering and trimming. 
More information on `PRINSEQ manual <http://prinseq.sourceforge.net/manual.html>`_.

-----

**Input**

The input file is sequence file in fastq format (sequences and quality)::

    @HWI-M00234:263:000000000-ADM55:1:1101:7508:4067 1:N:0:ATCACG
    GGTGCACTAGGATCGTAGTTGGCTACTTTCCCGTTTTCAATGTATACGCAAGGTACACGGTCAGCGGT
    +
    CCCCCGFGED8DDCAFDAEE9DFGGGG9CFAFFCC@@CFGFGGCGFGG>GGGFFGDGEFFEFG8>4GF

-----

**Parameters**

The parameters are numerous in PRINSEQ given the wanted treatments.

Several filter treatments are proposed:

 - Filters based on sequence length 
 - Filters based on quality score
 - Filters based on base content

And several trimming treatments eliminate sequence parts:
  - Trim of ends
  - Trim of tails
  - Trim based quality score

All these treaments can be customed using the proposed parameters.

-----

**Output**

The output file is a sequence file with sequences and quality from input file
which have undergone filter and trimming.
