PPI-weighted gene-set distance. Two gene-sets A and B contain 10 and 20 genes, respectively, and share six genes. Red lines indicate PPIs between A-B and B-A, and blue lines, PPIs between A-B and A ∩ B. Here, all the PPI scores are simply assumed to be 1. Right table shows how to calculate pMM distance, and compares with MM distance value
