(A) Comparison among different normalization factors. NFLogMean (x-axis) is plotted against SF (red open triangle) and NFMedian (black closed circle). The correlation between NFLogMean and NFMedian is higher (R = 0.971) than that between NFLogMean and SF (R = 0.918). (B) The NF score, NFscore, for SF (red open triangle), NFMedian (blue open diamond) and NFLogMean (black closed circle) is expressed as a function of respective 'true NF'. NFTrimLogMean is not shown here to simplify the graph since it is similar to NFLogMean. See also in Methods.
