Hey Guys,
this is a new plugin to download sra archives in an easy way, I hope :-)

Why ? because I need to download some file from SRA and I don't want to type the wget/curl command and I want to explore the ftp from command line, then because I need to start the downloads in background on a remote server.

Where ? https://github.com/helios/bioruby-sradl

as usual is experimental so, please be careful. I'm quite lazy so test section doesn't exist and the code needs some refactoring; I know I'll add it soon.
The DSL needs to be improved.

The procedure is recursive so you can download a bunch of reads at the same time.

By default the reads downloaded are the LITE. In the read me there is an example of looking for a regular archive: it's also an example of using optional parameters in thor' scripts.
To post process SRA format you need the sra tools kit

This plugin has also the purpose to be demonstrative for a Thor application.

This could be added to our NGS ngs section.

Any suggestion is welcome.

Ciao.
