+**What it does**
+
+Bowtie_ is a short read aligner designed to be ultrafast and memory-efficient. It is developed by Ben Langmead and Cole Trapnell. Please cite: Langmead B, Trapnell C, Pop M, Salzberg SL. Ultrafast and memory-efficient alignment of short DNA sequences to the human genome. Genome Biology 10:R25.
+
+.. _Bowtie: http://bowtie-bio.sourceforge.net/index.shtml
+
+A generic "Map with Bowtie for Illumina" Galaxy tool is available in the main Galaxy distribution.
+
+However, this Bowtie wrapper tool only takes FASTQ files as inputs.
+
+The sRbowtie wrapper specifically works with short reads FASTA inputs (-v bowtie mode)
+
+------
+
+**OPTIONS**
+
+.. class:: infomark
+
+This script uses Bowtie to match reads on a reference index.
+
+Depending on the type of matching, different bowtie options are used:
+
+**Match on sense strand RNA reference index, multiple mappers randomly matched at a single position**
+
+Match on RNA reference, SENSE strand, randomly attributing multiple mapper to target with least mismatches, the polarity column is suppressed in the bowtie tabular report:
+
+*-v [0,1,2,3] -M 1 --best --strata -p 12 --norc --suppress 2,6,7,8*
+
+**Match unique mappers on DNA reference index**
+
+Match ONLY unique mappers on DNA reference index
+
+*-v [0,1,2,3] -m 1 -p 12 --suppress 6,7,8*
+
+Note that using this option with -v values other than 0 is questionnable...
+
+**Match on DNA, multiple mappers randomly matched at a single position**
+
+Match multiple mappers, randomly attributing multiple mapper to target with least mismatches, number of mismatch allowed specified by -v option:
+
+*-v [0,1,2,3] -M 1 --best --strata -p 12 --suppress 6,7,8*
+
+**Match on DNA as fast as possible, without taking care of mapping issues (for raw annotation of reads)**
+
+Match with highest speed, not guaranteeing best hit for speed gain:
+
+*-v [0,1,2,3] -k 1 --best -p 12 --suppress 6,7,8*
+
+
+-----
+
+**Input formats**
+
+.. class:: warningmark
+
+*The only accepted format for the script is a raw fasta list of reads, clipped from their adapter*
+
+-----
+
+**OUTPUTS**
+
+If you choose tabular as the output format, you will obtain the matched reads in standard bowtie output format, having the following columns::
+
+    Column    Description
+  --------    --------------------------------------------------------
+   1 FastaID  fasta identifier
+   2 polarity + or - depending whether the match was reported on the forward or reverse strand
+   3 target     name of the matched target
+   4 Offset   O-based coordinate of the miR on the miRBase pre-miR sequence
+   5 Seq      sequence of the matched Read
+
+If you choose SAM, you will get the output in unordered SAM format.
+
+.. class:: warningmark
+
+if you choose BAM, the output will be in sorted BAM format.
+To be viewable in Trackster, several condition must be fulfilled:
+
+.. class:: infomark
+
+Reads must have been matched to a genome whose chromosome names are compatible with Trackster genome indexes
+
+.. class:: infomark
+
+the database/Build (dbkey) which is indicated for the dataset (Pencil - Database/Build field) must match a Trackster genome index.
+
+Please contact the Galaxy instance administrator if your genome is not referenced
+
+**Matched and unmatched fasta reads can be retrieved, for further analyses**
