Comparison of ordinary coverage correlation versus FPCA-based correlations. Scatterplot of Pearson coverage-based correlation coefficients and maximum FPC-based Pearson correlation coefficients between the scores of H1 hESC line at TSSs. Color scale indicates the correlation of the corresponding underlying eigenfunctions. Shape code denotes the order of the pairs of eigenfunctions. Chromatin modifications discussed in the main text have been labeled. No change between the two measures is represented by the black line. All data can be found in the Additional file 1
