agilp: Extracting and preprocessing Agilent express arrays
The current version contains a single function, AAProcess.
AAProcess extracts the raw median signals from green and red
channels of Agilent scanner array files. It replaces values for
replicate probes by the mean of all replicates, and
(optionally) removes control probes It log2 transforms data ,
and outputs txt files containing the red and green channel data
separately. It then normalises each set of data against a
baseline file (typically median or mean of a large set of
arrays, using LOESS regression. Finally outputs the normalised
data. The normalisation step can be optionally omitted.
