Normalisedaveragepeaksignal-methods: Retrieve normalised average peak profiles

In genialis/ChIPQC: Quality metrics for ChIPseq data

Retrieve normalised average peak profiles

Description

Retrieve normalised average peak profiles

Methods

signature(object = "ChIPQCexperiment")

Retrieve a matrix of normalised average peak signal data for all samples in a ChIP-seq experiment. Each column represents a sample, and each row a base pair position, centered on peak summits.

signature(object = "list")

Retrieve a matrix of normalised average peak signal data for all samples in a list of ChIPQCsample objects. Each column represents a sample, and each row a base pair position, centered on peak summits.

signature(object = "ChIPQCsample")

Retrieve a vector representing the normalised average peak profile for a sample. Each column represents a basepair position, centered on the peak summits.
