hi,

In the package Agi4x44PreProcess  I took the expression value as *MeanSigna*l,
then by the method *BGandNorm,* the background subtraction and the
normalization between the array is done.But the array should be normalized
within the array also first.This the script what is given in
Agi4x44PreProcess for normalization.I didnt find any option for within the
array normalization.

> ddNORM = BGandNorm(dd, BGmethod = "half", NORMmethod = "quantile",
+ foreground = "MeanSignal", background = "BGMedianSignal",
+ offset = 50, makePLOTpre = FALSE, makePLOTpost = FALSE)

please help me out how can we do the normalization within the array before
between the array normalization for one color agilent array.

thank you.
