Figure 7From: Methodological study of affine transformations of gene expression data with proposed robust non-parametric multi-dimensional normalization methodTransformation of background signal. Transformation of background signal. Left: An M versus A scatter plot where background signals (blue triangles) and foreground signals (red circles) lye along the same curve, which is evidence that both have been transformed identically. Right: A zoom-in of the left graph. Data is from [50].Back to article page
