WebMay 25, 2024 · The q-value is an adjusted p-value through Benjamini-Hochberg procedure. In general, q-value=0.05 is more stringent than p-value=0.05, and that's why you will get more peaks using the same number as p-value cutoff. To select a proper p- or q-value cutoff for peak calling is always a challenge.
