Figure 3.

Differences in the distribution of the occurrence frequency of transcription factors at different thresholds (relaxed and strict). The comparison of occurrence frequencies of the four transcription factors (GATA-3, Ets-1, TCF-1 and E2F) for different thresholds. The axes are same as at the Figure‚ÄČ1. The top row is the z-score distribution at a strict threshold. The second row is the z-score distribution with relaxed threshold. In all these plots we can see two distinct peaks and the depression area around the peaks. The straight blue horizontal line shows the expected occurrence frequency OFr from the shuffled dataset.
