Flow chart representation of the first steps of POSGODA. A simplified representation of the flow chart of the function used to select independent classes, to define the multiple testing corrected p-value signal levels, and to define the class outcome closest to the signal level. Input parameters and data are represented with light blue, intermediate steps are represented with green and end states are represented with gray. Steps associated with numbers are explained in the text. For more detailed un-simplified representation see the supplementary text.
