BREC: an R package/Shiny app for automatically identifying heterochromatin boundaries and estimating local recombination rates along chromosomes

Table 1 BREC HCB compared to reference boundaries from the reference genome of D. melanogaster

The shift is the absolute value of the distance between the BREC and the reference physical heterochromatin boundary. The first five rows represent all chromosomal arms. Grouped columns present reference, BREC and shift values for the centromeric boundaries (Columns 2–4), and for the telomeric boundaries (Columns 4–6). Here the boundary values correspond to the internal HCB. The external boundaries are represented by the physical positions of the first and the last markers of the chromosomes. All values are expressed in Megabase (Mb). The asterisk indicates the largest shift value reported on centromeric and telomeric boundaries separately (see corresponding Additional file 3). The last four rows represent general statistics on the shift value. From top to bottom, they are minimum, maximum, mean, and median respectively. See details on the shift metrics in "Validation metrics" section
