Does any one know how to extract SRX ids from SRR ids. Thanks.

ex:

***Input***

    SRR1294518

***Output***

    SRR1294518  SRX549132
<p>Have a look at the SRAdb package in Bioconductor. You do have to download the SRA database backup (I suspect there&#39;s a way to remotely query it, but perhaps not). Then you can use the sraConvert() command. This also allows you to download datasets associated with a run/sample/whatever easily.</p>
