This plot shows the high quality autosomal alignment (HQAA) fragment length distribution (FLD) of each experiment. The canonical ATAC-seq FLD has a sharp peak at short (50-100bp) fragment lengths, and broader peaks at fragment lengths that would span one, two or three nucleosomes.
Switching the y axis scale to exponential can reveal nucleosomal periodicity at higher fragment lengths.

The dashed red line is the reference fragment length distribution (). You can toggle it on and off.
You can smooth the lines to make it easier to compare experiments, or make the plot more responsive if you have a lot of data. By default, smoothing is set to 10. For the most accurate plot, choose a smoothing value of one.
