Figure 4.

Comparison of known versus discovered motifs (selected where discovered better enriched than known; all factor groups with a discovered motif matching a known motif in Supplementary Table S3). Displayed is the known and discovered motif with the maximum enrichment across all data sets for a factor group. Only the discovered motifs that match a known motif for a factor group are considered. The maximum enrichment is indicated for each factor and, in parenthesis, the ‘raw’ enrichment for the same data set without the use of the shuffle motifs for correction.
