Accuracy of MEA methods using fixed Y partitions. The ability of different MEA methods to correctly rank the known TF motif in 237 yeast ChIP-chip experiments is shown. Each point corresponds to the mean (Panel a) or the median (Panel b) percentile rank accuracy (PRA) of an MEA method on all ChIP-chip datasets that contain at least one sequence with a fluorescence p-value less than the value of t _y (X-axis). Increasing X values correspond to relaxing the threshold for a sequence to be considered bound by a TF. To the right of the vertical line, all 237 sets are included; to the left, increasingly fewer sets are included at stricter t _y thresholds.
