Takes a vector of probeset names and a CDF name. Produces a table of annotations, containing gene name, description, sequence accession number and unigene accession number for each probeset. In addition, write.annotation is a utility function that outputs the annotation data in a form suitable for loading into excel and results.summary takes the outut of pairwise.comparison or pairwise.filter and spits out a table with the means of the replicates the fold-change between them (log2) and t-test p-values. This is followed by a table of annotation (produced by get.annotation).
