<p>I was trying to download some data from NCBI SRA <strong>(SRA059451)</strong>. There are 27 samples available for <strong>SRA059451</strong>. But i am unable to understand which samples are <strong>'control'</strong> and <strong>'test'</strong> samples. Please help me regarding how to differentiate the samples.</p>

Seems to be [cross-posted](https://www.biostars.org/p/427741/) on Biostars, which is fine but please refer both posts to each other so that answers on one site would be utilized by the other community.
