WebThe peak calling step detects enriched protein-DNA interaction regions on the genome. Basepair’s ChIP-seq pipeline uses MACS2 to perform this analysis. In MACS2, peak calling is performed based on three main steps: fragment estimation, followed by identification of local noise parameters and then peak identification. WebMay 1, 2024 · Peak calling is one of the first steps in the analysis of these data. Peak calling consists of two sub-problems: identifying candidate peaks and testing candidate peaks for statistical significance. We surveyed 30 methods and identified 12 features of the two sub-problems that distinguish methods from each other.
