Access methods for chipMean slot in parameterOptions object.

Description

Access methods for chipMean slot in parameterOptions object.

Usage

chipMean(object)<-value

Arguments

object	object is a parameterOptions object.
value	value is a positive numeric value that will be assigned to the chipMean slot. chipMean describes the average size of a ChIP-seq peak in base pairs.

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 parameterOptions object.

Value

Returns a parameterOptions object with an updated value for chipMean slot.
