A screenshot of the DiscoverySpace Venn table. In the example above the user has specified five sets of tag sequences from CGAP SAGE libraries and has selected and dragged them into the Venn table. Four of the sets are tag sequences from breast cancer libraries, the fifth, CGAP 647, is from a normal breast sample. The user has raised the quantitative cutoff to 2 or above in order to exclude singleton tag sequences, and has then excluded any tags in the normal set and has selected the intersection of the other cancer sets. The resulting sets of tags are selected from the table and are dragged out for further analysis in the DiscoverySpace Explorer.
