Peaks are analyzed in two different ways: differential and individual. Individual peaks do not consider the overlap between peaks to be compared and is essentially a peak calling on individual conditions. Differential peaks are compared based on an overlapping peak called in two conditions. In this case all 4 data groups (WT EXP and 2 inputs) are used in the comparison.
Peaks are called with two different set of window parameters when SICER is concered. Examples:
