Fig. 1From: Simulation of a medication and methylation effects on triglycerides in the Genetic Analysis Workshop 20A 3D indexing order of the GAW20 simulation. The j index in the figure represents the subjects, the i index is noting the causal SNPs, where i = 1–5 also indexes the 5 main effects of the corresponding nearby CpG sites, while the sites 6–105 are 100 SNPs with background genetic effects. The k index indicates replications (k = 1, 2, …, R = 200)Back to article page
