Histogram showing the precision of finding proximal bi-labels. For simulated human Rmap data, we found proximal bi-labels for all extracted bi-labels. We designate a proximal bi-label found to be a true positive if its true location in the genome is the same as the location of the bi-label to which it is proximal—and false positive otherwise. Next, we plotted a histogram showing the distribution of true positives and false positive proximal bi-labels for each bi-label. We show that high frequency bi-labels i.e. bi-labels for which we find more proximal bi-labels produce more precise proximal bi-labels. This justifies filtering low frequency bi-labels
