An object of class AffyBatch OR
An AnnotatedDataFrame object
A cluster object obtained from the function makeCluster in the SNOW package.
A logical value. If
bgCorrectPara is the parallelized function for background correction of probe intensities.
For serial function an more details see bg.correct.
For using this function a computer cluster using the SNOW package has to be started.
Starting the cluster with the command
makeCluster generates an cluster object in the affyPara environment (.affyParaInternalEnv) and
no cluster object in the global environment. The cluster object in the affyPara environment will be used as default cluster object,
therefore no more cluster object handling is required.
makeXXXcluster functions from the package SNOW can be used to create an cluster object in the global environment and
to use it for the preprocessing functions.
AffyBatch for which the intensities have been background adjusted. For some methods (RMA), only PMs are corrected and the MMs remain the same.
