Scatter plots of the fold-change estimates between two platforms and the correlation coefficients. The fold change estimates in the plots was the larger of the A/B or B/A. The two lines represent a 2-fold change. The points in the lower right or upper left region have a 2-fold change in one platform and less than 2-fold change in the other platform. The six plots represent the 10 possible plots and include the largest and smallest correlations.
