The National Resource for Network Biology (NRNB) aims to advance network biology science through bioinformatic methods, software, infrastructure, collaboration, and training. In the past year, the NRNB made progress in its specific aims, including developing new network analysis methods, catalyzing changes in network representation, establishing software and databases, engaging in collaborations, and providing training opportunities. Going forward, the NRNB plans to further develop methods for differential and predictive network analysis, multi-scale network representation, and pathway analysis tools.
