sequencing (ChIP-Seq) is getting popular to study +genome-wide protein-DNA interactions. To address the lack of powerful ChIP-Seq +analysis method, we present a novel algorithm, named Model-based Analysis of +ChIP-Seq (MACS), for identifying transcript factor binding sites. MACS captures +the influence of genome complexity to evaluate the significance of enriched +ChIP regions, and MACS improves the spatial resolution of binding sites through +combining the information of both sequencing tag position and orientation. MACS +can be easily used for ChIP-Seq data alone, or with control sample with the +increase of specificity. + +View the original MACS2 documentation: +https://github.com/taoliu/MACS/blob/master/README.rst + +------ + +**Usage** + +**Peak Calling**: Main MACS2 Function to Call peaks from alignment results. + +**Compare .bdg files**: Deduct noise by comparing two signal tracks in bedGraph. + + +------ + +**Citation** + +For the underlying tool, please cite Zhang Y, Liu T, Meyer CA, Eeckhoute J, Johnson DS, Bernstein BE, Nusbaum C, Myers RM, Brown M, Li W, Liu XS.
