narrowpeak data from wig files?

[john789]

Hi

I've downloaded some chip-seq data from geo (http://www.ncbi.nlm.nih.gov/geo/) and the only option is .wig format. I'd like the data in an 'ENCODE narrowPeak' style; i.e. something like

chromosome start stop strand score p-value

The original paper used macs for peak finding but it seems wig files are output from this tool not input! Can anyone tell me how to get .wig data into a peak list format I can make use of?

Many thanks
John

Narrow peaks in ChIP-seq WIG files

Hi John,

The Bioconductor package NarrowPeaks

http://bioconductor.org/packages/release/bioc/html/NarrowPeaks.html

is able to do what you mention. It takes a WIG files and analyzes the shape of candidate regions over a continuum to identify narrow peaks.


Best,
P
