Comparison of the reference normalized contact probabilities (CPs) (a and b) with the recovered CPs (c and d), obtained with the IBD method for K562 and GM12878, respectively, at Nf = 0. The value of interaction strength parameter εμν is shown for the (e) K562 (ON state) and (f) GM12878 (OFF state) cell lines, respectively, at the converged state.
