What does "0" correspond to in the signal heatmaps?

Hi -

Does "0" on the x-axis of the signal heatmaps correspond to peak summit or peak center (or TSS)?

Thanks!

Hi, 0 is the center of each assessment region, which are created by overlapping peaks. If you only have 1 peak file then they would be the peak center. Assessment regions are also resized to a consistent size when analyzing signal, 3kb by default.

The peak summit position is not used.

Thanks for the questions!
