Domain sets at various resolutions. 10 best optimal and near-optimal solutions for resolutions γ=0.5,0.35,0.15,0.10 for a portion of human fibroblast chromosome 20 (IMR90). Variations in the domain assignments within a single γ and across resolutions correspond with visually identifiable, hierarchical regions of dense Hi-C interactions. All histone mark tracks were obtained from IMR90 cells. Plotted with WashU EpiGenome Browser .
