This tool is incredibly, intentionally naïve, and will crash if there are missing ranges in some bigwig files. This feels like a reasonable assumption to make (simplifies processing) at the expense of theoretical correctness, given that when you are stacking histograms they're probably coming from the same upstream pipeline with the same settings (i.e. step/width/etc.)"/>
