WebThe analysis for ChIP-seq data is to predict the regions of the genome where the ChIPed protein is bound by finding regions with peaks. A fine balance between sensitivity and specificity depends on choosing an appropriate peak-calling algorithm and normalization method based on the type of protein ChIPed. WebPeak calling¶. R2 provides a couple of algorithms to assess significant enrichment ChIP between experiment and control.First is the MACS algorithm; this is often used in ChIP-seq data analyses and publications.

WebJul 8, 2010 · ChIP-seq peak finders must discriminate these true peaks in sequence coverage, which represent protein binding sites, from the background sequence. When examining tag density across the genome, it is important to consider that sequence tags can represent only the 5′-most end of the original fragment due to the inherent 5′ to 3′ nature … Peak calling is a computational method used to identify areas in a genome that have been enriched with aligned reads as a consequence of performing a ChIP-sequencing or MeDIP-seq experiment. These areas are those where a protein interacts with DNA. When the protein is a transcription factor, the enriched area is its transcription factor binding site (TFBS).
