267 **What it does**
|
|
|
268
|
|
|
269 With the improvement of sequencing techniques, chromatin immunoprecipitation followed by high throughput sequencing (ChIP-Seq)
|
|
|
270 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
|
|
|
271 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
|
|
|
272 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.

|
276 ------
|
|
|
277
|
|
|
278 **Usage**
|
|
|
279
|
|
|
280 **Peak Calling**: Main MACS2 Function to Call peaks from alignment results.
|
|
|
281
|
|
|
282 If you choose "Scores in bedGraph files" MACS will output the fragment pileup, control lambda, -log10-pvalue and -log10-qvalue scores in bedGraph files.
|
|
|
283 The peaks in BED format contain the following colomns: chr end length abs_summit pileup -log10(pvalue) fold_enrichment -log10(qvalue) name
|
|
|
284
|
|
|
285 **Compare .bdg files**: Deduct noise by comparing two signal tracks in bedGraph.
