chipMean {ChIPanalyser}R Documentation

Accessor method for chipMean slot in a occupancyProfileParameters object.

Description

Accessor method for chipMean slot in a occupancyProfileParameters object.

Usage

chipMean(object)

Arguments

object

object is a occupancyProfileParameters

Details

Default vlaue : 150 When computing ChIP-seq like profiles (computeChipProfile, the occupancy values given by computeOccupancy are transformed into ChIP-seq like profiles. The average size of a ChIP-seq peak was described by Kaplan (Kaplan et al. , 2011). It is advised to use the average width of ChIP peaks from actual ChIP-seq data. We strongly encourage to set values when building a occupancyProfileParameters object.

Value

Returns chipMean slot from a occupancyProfileParameters object.
