Figure 5.

Accuracy of a partition-free MEA method. The ability of different MEA method to correctly rank the known TF motif in 237 yeast ChIP-chip experiments is shown. Each bar shows the mean PRA of the given MEA method on all 237 ChIP-chip datasets. Error bars show standard error. The LR method is partition free. PASTAA uses X and Y constrained partition maximization with a maximum of 1000 sequences in the "positive" sets. All fixed-partition (YFP) methods use a threshold of t_y = 0.001.
