 # wk-shell-decomposition
 
-wk-shell-decomposition is a Cytoscape 3 app that performs a k-shell decomposition on a network using a novel weighted algorithm. k-shell decomposition is a method that ranks the most important nodes in a network and partitions them into shells based on that rank. This novel algorithm assigns a weight based on the degree of a node and the adjacent nodes. This app will generate a column _wkshell on the network's node table that stores the rank and partitions the network into ordinal k-shells. This app can be run by accessing it under the apps menu or by calling the command:

This novel algorithm assigns a weight based on the degree of a node and the adjacent nodes. This app will generate a column _wkshell on the network's node table that stores the rank and partitions the network into ordinal k-shells. The app then adjusts the layout of the network to packed concentric rings sorted by k-shell and applies a gradient to the color of the nodes by k-shell.
