FlaiMapper wrapper for Galaxy
=============================

Fragment Location Annotation Identification Mapper

FlaiMapper: computational annotation of small ncRNA-derived fragments using RNA-seq high-throughput data.


Input
-----

Alignment
*********

This file has to contain aligned single end reads from a small RNA-Seq experiment, provided in the BAM format.

Prior to running FlaiMapper, it is common to align sequencing reads to either:

- mature ncRNA sequences
- all chromosomes

Example- and reference data
***************************

The reference sequence should be provided in FASTA format.

You can access **ncRNAdb09** FASTA file at the following URL:
https://raw.githubusercontent.com/yhoogstrate/flaimapper/master/share/annotations/ncRNA_annotation/ncrnadb09.fa *(reference file)*

If you want to test FlaiMapper with example data you can obtain several
alignment files from the following directory tree:

https://github.com/yhoogstrate/flaimapper/tree/master/share/small_RNA-seq_alignments

More details are given in the manual at the following website:
