In panel A and B there is no correlation between the PM and MM signals as can been seen by the low slope and Pearson correlation coefficient. This in contrast to results in panel C and D were the slope and Pearson correlation coefficient are large. These signals are obtained from the microarray scanner and are the input for the six calculation methods
