YOKOFAKUN: Inside the variation toolkit: Generating a structured document describing an Illumina directory.

I wrote a tool named "Illuminadir" : it creates a structured (JSON or XML) representation of a directory containing some Illumina FASTQs (I only tested it with HiSeq , paired end-data and indexes).

Motivation

Illuminadir scans folders , search for FASTQs and generate a structured summary of the files (xml or json).
Currently only tested with HiSeq data having an index

Compilation

Options

Option	Description
IN=File	root directories This option may be specified 1 or more times.
JSON=Boolean	json output Default value: false. Ouput, could be used with jsvelocity https://github.com/lindenb/jsvelocity

Example

$ java  -jar dist/illuminadir.jar \
	I=dir1 \
	I=dir2 | xsltproc xml2script.xslt > script.bash
(...)

XML output

The XML ouput looks like this:

<?xml version="1.0" encoding="UTF-8"?>
