This app is an application of the ModuLand method family ([http://www.plosone.org/article/info%3Adoi/10.1371/journal.pone.0012528 PLoS ONE, 7, e12528]) determining and visualizing overlapping network modules (clusters/communities) by calculating the assignment strength of each node to each discovered module. The app builds the hierarchy of network modules, where meta-nodes of the higher layer are the modules of the lower layer. The app also calculates a number of topological measures such as community centrality, bridgeness and overlap, characterizing the centre of modules, as well as intermodular nodes between two or more modules, respectively.
The app is further described here: Szalay-Beko, M., Palotai, R., Szappanos, B., Kovács, I.A., Papp, B. and Csermely, P.
