MA plots: individual array quality of each dataset after normalization. M = log2 (I1) − log2 (I2), A = 1/2 [(log2 (I1) + log2 (I2)], where I1 is the intensity of the array studied and I2 is the intensity of a “pseudo-array” that consists of the median across arrays. Typically, we expect the mass of the distribution in an MA plot to be concentrated along the M = 0 axis, and there should be no trend in M as a function of A
