Determination of 7 non-intersecting TFB binding site data sets. Each colored section of the three-circle Venn diagram contains the number of ChIP-seq peak centers determined for each of three GTFs TfbB, TfbD, and TfbG. Peaks were resolved at a peak-to-peak center distance of 30 nt. Sequence entries were created by extracting a continuous block of sequence centered at each of the ChIP-seq peaks (each peak produces one sequence entry). Each of the colored segments of the diagram refers to a different data set of sequences. All determined peaks and corresponding sequence entries were limited to exist in only one of the 7 possible data sets.
