Comparisons of sLADs and LADs in MEFs. (A) A 400 kb segment in chromosome 1 shows that a LAD region is comprised of an array of sLADs and non-sLADs. Genome browser tracks follow the same scheme displayed in Figure 1A. (B-D) Bar plots of (B) log2 seq ratios, (C) LmnB1 read densities (RPKM) and (D) Dam read densities (RPKM) among genomic regions that belong to both LADs and sLADs (common sLADs/LADs), LADs but not sLADs (LAD-only regions), sLADs but not LADs (sLAD-only regions) and neither LADs nor sLADs (common non-sLADs/non-LADs). The upper and lower box boundaries indicate the 25th and 75th percentiles of the data, respectively. The upper and lower bars indicate the first and 99th percentiles, respectively. The median values are shown in parentheses.
