bookmark RNAiCut Discovers genes involved in a biological process. RNAiCut employs the connectivity of subgraphs of protein-protein interaction (PPI) networks to find score thresholds from functional genomic data. It allows hit-list gene selection with orthogonal datasets. This tool calculates the edge count of induced subgraph and determines the P-value of finding a PPI subgraph. It is useful for functional genomics research.
