+**What it does**
+
+This tool uses a specie-specific GFF3 file from mirBase_ to guide the parsing of an alignment file produced with the sRbowtie tool.
+
+.. _mirBase: ftp://mirbase.org/pub/mirbase/CURRENT/genomes/
+
+------
+
+.. class:: warningmark
+
+the Guide GFF3 file must be in the following format:
+
+2L	.	miRNA_primary_transcript	243035	243141	.	-	.	ID=MI0005821;Alias=MI0005821;Name=dme-mir-965

+
+With name for mature miRNA (3rd column = miRNA) containing either the -3p or -5p string in the attribute Name (Name=dme-miR-965-3p, for instance)
+
+------
+
+**Input formats**
+
+1. One or sereral alignment files generated with sRbowtie tool and **renamed** according to the name of the biosample (avoid spaces in biosample labels)
+
+.. class:: warningmark
+
+Alignment datasets generated with sRbowtie must be renamed according to a biosample name
+
+2. A GFF3 file retrieved from mirBase_
+
+------
+
+**Outputs**
+
+Two count list files for counts of reads aligned to pre-mir or mature miRNA
+
+A pdf of pre-mir coverages. Red coverages indicate that the mir gene is in the genomic up strand, blue coverages indicate that the mir gene is in the genomic down strand.
