Power Graph Analysis with CyOog
Matthias Reimann
Biotechnology Center, Technische Universität Dresden, Germany
Biological Use Case:
General: Analysis of gigantic biological networks like protein interaction networks, sequence homology networks, or regulatory networks. The information you are looking for in such networks is hidden by a big mass of edges -- inside a 'fur ball' or 'hairy monster'. Instead of loosing valuable details in the networks by coarse-graining them using clustering techniques, Power Graph Analysis can be used. A power graph is a compressed version of a normal graph. The used transformation is completely reversible.
Example described here: Finding functional relationships among transcription factors in a huge regulatory network.
