Overlapping analysis of the datasets. A. Hierarchical clustering of the 168 datasets for 56 TFs based on their pair-wise binding peak overlapping scores S
. The blow-ups show two clusters for cooperative TFs (see Results). B. The motifs of TFs KR and HB are both found in the overlapping datasets GSM511084_Dmel-KR1 ChIP-ed by KR and GSM511081_Dmel-HB1 ChIP-ed by HB.
