WebMar 24, 2024 · Ideally, Blacklists and Greylists will be applied to the aligned reads prior to calling peaks, as removing reads in anomalous regions will yield better background noise models. Once greylists have been generated, peaks can be re-called and read into DiffBind. Author(s) Rory Stark with thanks to Gord Brown References. Amemiya HM, … WebDiffBind supports the use of spike-ins, where the reads used to normalize the libraries are based on those aligned to exogenous chromatin (eg. from Drosophila melanogaster), or are identified as peaks associated with a …

I have histone, broad-peak data, however some of the peaks are actually rather narrow. So what I can see happening is that the broader peaks are being nicely identified as differentially expressed by diffbind, but the narrow peaks which seem highly up-regulated (with big fold changes) are not ...

Normally, DiffBind is used for ChIP-seq data, but I've seen it used for ATAC-seq as well. I don't see any issues with that. MACS can be used for the initial peak calling. However, when performing peak calling for ATAC-seq data, it is advised to adjust the default parameters so peaks are centered on the cutting sites. magic editing photo
