Figure 2.

Fountain plot comparing retrievals from NetAffx_Q and DAVID_Q. Horizontal axis: For each UniProt ACC, the number of probesets retrieved from NetAffx _Q (left of zero) and DAVID _Q (right of zero). Vertical axis: Each horizontal slice is one ACC (11,879 slices are stacked). ACCs were categorized, and the probeset counts for each ACC graphed by category, sorted within category by intersection size, then by total size. Category definition example: "excess left" is the set of ACCs such that both probeset retrievals were non-empty, and {probesets retrieved by NetAffx _Q} is a strict subset of {probesets retrieved by DAVID_Q}.
