Description of the Lucidea array. The Lucidea array has 9,600 spots from 20 genes; each gene was replicated 480 times. Eight genes were spiked with different mRNA-concentrations in the treated and reference channels (i.e. the DE-genes, red dots 11–18). The remaining 12 genes were spiked equally in both channels at different mRNA-concentrations (i.e. the NDE-genes, blue dots 1–10). Three NDE-genes, two expressed at concentration zero and one at concentration one, were clustered together and are in this paper treated as one gene.
