Usage

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

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