Metadata Search Use Case

In this scenario, a researcher would like to know: what differences are observed in T cell repertoires between child siblings? 

They enter the metadata search workflow and filter their results by Study Title ("child"), Study Type ("healthy"), and Cell Subset ("T Cell, Naive CD4+").

Results are returned from a paper on siblings' T cell repertoires from the iReceptor Public Archive in Vancouver, Canada

The researcher selects from the Individual Samples list sibling Sample IDs ("Child B1, Child B2")

They download the resulting ~7,000,000 sequences for further analysis.
