Generates a graphic of the 50 best probesets of the algorithm. Every probeset is plotted in function of the number of samples in the subpopulation that overexpressed it and delta (difference of expression between max of normal samples and median of the subpopulation). They are represented by a circle, with a size proportional to 1/(standard deviation of expression in the subpopulation)
