Z-scores are computed for the experimental area under ROC or PRC based on distributions of the random areas under these curves
Seeds: Genes where diffusion signal starts FROM)
Recipients: Genes that receive the diffusion signal and that are in the other validated group
Random genes are selected either uniformly or degree matched
