Figure 2.

MA plots of the MAS5 and RMA processed data showing probesets selected for real time PCR. Light grey points all data. Circles: PA probesets. Diagonal Crosses: AA-RMA probesets. Triangles: AA probesets. Vertical Crosses: PP probesets. RMA reports the fold change for the PA, AA and AA-RMA probesets as low in comparison to MAS5. AA and PA probesets are of low intensity. Additional MA plots, stratified by detection call can be found in the supplementary data.
