Before revision: Network enrichment analysis (NEA) is a powerful method, that integrates gene enrichment analysis with information on dependences between genes . Existing tests for NEA rely on normality assumptions, they can deal only with undirected networks and are computationally slow .
After revision: Network enrichment analysis (NEA) is a powerful method, that integrates gene enrichment analysis with the information on relationships between genes that is provided by gene networks . Existing tests for NEA rely on normality assumptions, they can deal only with undirected networks and are computationally slow .
