Visualization of the biclustering result for active promoters in GM12878 cell-line a ChIP-seq tracks (rows) and promoters (columns) are ordered according to the biclustering and displayed as a heatmap. The heatmap color corresponds to normalized peak height (see the “Methods” section) b Result of t test measuring cluster association for each row. The bars extend to the right to a height of the negative logarithm base 10 of the p value. A high t test value for a row and a certain cluster indicates that this row’s HM/TF is enriched in the respective cluster
