Detection call p-values for Affymetrix low level spike-in experiment

Four different concentrations (0, 0.75, 1.5, 3 pM) of genes were spiked in groups (group size 6-7 transcripts) Each concentration combination were spiked into a common backgroung sample (HeLa cell line) and hybridized to three HG-U133A Plus 2.0 Arrays.
