Matrices of consensus in the most significant changing genes (Z-score) in the 45 different protocols for GSE1004, for different cutoffs: (a) Top 400 genes. The blocks on consensus are labelled LW, RMA and MAS to indicate the choice of expression measure.; (b) 400 genes. We have labelled the next level of structure None, RMA and MAS, and this level indicates the choice of background subtraction.; (c) Top 100 genes ; (d) Top 30 genes
