Data Normalization

Description

This function performs basic normalization on unpaired data.

Usage

normalize.data(data, center=TRUE,loess.cor = FALSE)

Arguments

data A gene expression data object. The result of build.data function
center Logical. If True each array*condition is centered to have a 0 mean log-intensity.
loess.cor Logical. If True a lowess normalization is performed globally on each array.

Details

The normalization is only centering of the gene expression per array and per condition. After normalization all arrays have a mean expression level of 0 in both channels.

Value

This function add the following elements to the gene expression data object :

cond1 Matrix of normalized gene expression in condition 1
cond2 Matrix of normalized gene expression in condition 2
