- MACS: Model-based Analysis of ChIP-Seq
- Next generation parallel sequencing technologies made chromatin
- immunoprecipitation followed by sequencing (ChIP-Seq) a popular
- strategy to study genome-wide protein-DNA interactions, while creating
- challenges for analysis algorithms. We present Model-based Analysis of
- ChIP-Seq (MACS) on short reads sequencers such as Genome Analyzer
- (Illumina / Solexa). 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.
