# macs

## Summary

+ **Module Name:** macs
+ **Support Level:** Primary Support
+ **Software Access Level:** Open Access
+ **Home Page:** [http://liulab.dfci.harvard.edu/MACS/index.html](http://liulab.dfci.harvard.edu/MACS/index.html)

## Software Description

MACS empirically models the length of the sequenced ChIP fragments,
which tends to be shorter than sonication or library construction size
estimates, and uses it to improve the spatial resolution of predicted
binding sites. MACS also uses a dynamic Poisson distribution to
effectively capture local biases in the genome sequence, allowing for
more sensitive and robust prediction. MACS compares favorably to
existing ChIP-Seq peak-finding algorithms, is publicly available open
source, and can be used for ChIP-Seq with or without control samples.
