Frequency of specific density ratios of loop backbone versus the rest of the backbone for the loops that were used as template from homologous structures. Most template loops have sufficient density and therefore they would also have been built by Loopwhole: those loops are to the right side of the red line indicating the density ratio cutoff of 0.25.
