The correlation coefficient between cross-platform nucleosome positioning datasets. In the heat maps, the red number represents corresponding correlation coefficients between datasets. (A),(B) The correlation coefficients matrix of the six position datasets are plotted as heat maps [2-6,11], and (C), (D) The correlation coefficients matrix of the three occupation ratio datasets are plotted as heat maps[3,4]. (A) and (C) represent genome-wide correlations between datasets, whereas (B) and (D) represent promoter region correlations between datasets.
