Distribution of the test statistic and p-values of colocalization analysis for a collection of 477 genomic tracks with 2113.82 bp average segment length for histone modifications (hg19). [a and b shows the distribution of p-values of the colocalization analysis with (left) and without (right) exclusion of assembly gap regions under the null model. c and d shows the observed test statistic and the average test statistic of the same tracks with (left) and without (right) exclusion of assembly gap regions under the null model. Note: Both values are higher than 1 because the computations were performed relative to the whole genome size.]
