a, Correlation matrices of Hi-C maps of chromosome 1 right arm. b, Binary annotation of compartment A/B at chromosome 1 right arm. The y axis shows values of the eigenvector of the first component. Regions coloured in blue and red depict compartment A and B, respectively. c, Genome-wide A/B compartment annotation among different samples. c14, crwn1 crwn4; m, mock; h, heat. d, Distance-normalized interactions between compartment A and B relative to the average. Sample labels are as in c. Chromatin contacts within 1 Mb are included in the calculation. The box plots indicate the median (line within the box), the lower and upper quartiles (box), margined by the largest and smallest data points that are still within the interval of 1.5 times the interquartile range from the box (whiskers); outliers are not shown. n = 400 for individual box plots. p values indicate the two-sided Mann–Whitney U-test results.
