The ranking algorithm. a 2-d plot of the two measured distance: M1 is the distance from the upper wisker; M2 is the distance from the median. The “best” outliers lie on the top right corner of the graph, that corresponding to a major distance from both upper wisker and median, and are reported as red dots. b The metrics used for ranking are reported: M1 (red arrow) is the distance from the upper wisker; M2 (orange arrow) is the distance from the median; M3 (yellow circle) is the number of samples in which the gene has an outlier expression value
