CNetQ / Corbi 0.6-1 – Network Querying tool based on Conditional Random Fields

CNetQ / Corbi 0.6-1


CNetQ is an network querying tool based on conditional random fields.A large amount of biomolecular network data for multiple species have been generated by high-throughput experimental techniques, including undirected and directed networks such as protein-protein interaction networks, gene regulatory networks and metabolic networks. There are many conserved functionally similar modules and pathways among multiple biomolecular networks in different species, therefore, it is important to analyze the similarity between the biomolecular networks. Network querying approaches can efficiently discover the similar subnetworks among different species. However, many existing methods only partially solve this problem. A novel approach for network querying problem based on conditional random fields (CRF) model is proposed, which can handle both undirected and directed networks, acyclic and cyclic networks, and any number of insertions/deletions. The CRF method is fast and can query pathways in a large network in seconds using a PC.
