Test statistics were obtained using the GenometriCorrelation package in R/Biocunductor. For more information about the different tests see Favorov et al. 2012. Both KS (Kolmogorov-Smirnov) and Jaccard Measure p-values were obtained by permuting the obeserved results 10 000 times over the human genome.
