WebJun 5, 2024 · ChIP-seq Chromatin Immunoprecipitation (ChIP) is used to explore protein interactions with genomic DNA. Typically, chromatin is cross-linked to fix proteins to the DNA, sheared into small fragments and immunoprecipitated with an antibody which recognises the protein of interest (e.g. transcription factors, chromatin modifiers, histone … WebThe output file contains the scaled IDR value (min(int(-125*log2(IDR), 1000)) in the 5th field. If one wants to choose 0.05 as the IDR threshold to identify "reproducible" peaks, then this metric must be at least 540. awk '$5 >= 540 {print $0}' IDR.narrowPeak.bed > IDR.narrowPeak.filtered.bed dvd dean martin celebrity roasts

A major advantage of the IDR method is that it is independent of the peak-calling algorithms and can be applied to a variety of significance criteria ...
