Chromosome projection mandalas showing the proximity of each HERV-H provirus to the nearest site of H3K4Me3 on the chromosome, in human I3 ES cells, iPS-15b cells, and HeLa cells. Each dot on the mandala indicates an HERV-H provirus, as described in reference . The angular distance around the mandala indicates the linear position of each provirus on the indicated chromosome. The radial distance from the perimeter indicates the distance of the provirus from the nearest H3K4Me3 site, in log scale from 0 to 1 megabase. Blue dots are HERV-H proviruses within 2 kB from the nearest marker. Red dots are proviruses >2 kB away from the nearest H3K4Me3 site. The association strength (F score) is written under each Mandala. F score > 0.5 constitutes a significant association.
