FlaiMapper wrapper for Galaxy

Fragment Location Annotation Identification Mapper

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


Input
-----

Alignments
**********

Aligned reads from small RNA-Seq experiments have to be provided in the BAM format.
In case you add multiple BAM files, FlaiMapper will simply concatenate the data and perform one single analysis on the entire set of alignments.

Mask File
*********

There are two strategies to analyze using FlaiMapper:

- Relative to mature ncRNA sequences
- Relative to chromosomes

Therefore FlaiMapper requires a list of ncRNA annotations relative to the used reference genome for the alignment files. These ncRNA locations within the sequences provided in the FASTA file (MASK) regions should be provided in the GFF/GTF format:

- http://genome.ucsc.edu/FAQ/FAQformat.html#format3
- http://www.ensembl.org/info/website/upload/gff.html

If you are making use of a ncRNA database that has no GTF file available you can make use of the galaxy tool **flaimapper-gtf-from-fasta** to create one.


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

Fasta sequence
**************

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)*

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

To align reads to ncRNA you need aligner specific indexed version of the reference. We have made
the following available for ncRNAdb09:

 - **Tophat1**: https://github.com/yhoogstrate/flaimapper/blob/master/share/annotations/ncRNA_annotation/ncrnadb09.bt2.tar.gz
 - **Tophat2**: https://github.com/yhoogstrate/flaimapper/blob/master/share/annotations/ncRNA_annotation/ncrnadb09.bt2.tar.gz

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