Dear all,

I have searched through the bioconductor ducument and this mailing list, but
could not find a general guidance about how to correct background in cDNA
array data.  I have imported my data (GPR files from GenePix) using
functions from marray.  Now what are the available methods for background
correction before normalization?  Any suggestions/experience is very much
