  1. LEF density is given in terms of number of LEFs per kilobase pair; processivity is defined as the averaged LEF processivity in the corresponding region, in the absence of obstacles; cohesive cohesin density is also given in terms of number of cohesive cohesins per kilobase pair. Parameters are optimized to minimize the mean pairwise ratio (MPR). See Additional File 1: Methods for details of statistical error calculation and the optimization process
