Hello, This line is an optional feature that can be configured on the track's description page. It is designed to help with visualizations. The exact thresholds of what to consider significant will depending on the experiment and the questions you are using it to answer. We hope that this helps. If more information comes in today about this specific data set, we will send an update.

Is this a experimental threshold? Can the peaks that are seen below this line considered positive reads? Thanks!
