This table summarizes the collection of default attributes that are currently included in EpiGRAPH. Due to different degrees of annotation, the numbers differ between the genomes of human (hg18 and hg17), mouse (mm9), chimp (panTro2) and chicken (galGal3). EST, expressed sequence tag; SNP, single nucleotide polymorphism.
