+
+**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 proposed parameters.
+
+-----
+
+**Output**
+
+The output file is a sequence file with sequences and quality from input file
+which have undergone filter and trimming.
