HotNet is an algorithm for finding significantly altered subnetworks in a large gene interaction network. While originally developed for use with cancer mutation data, the current release of HotNet also supports any application in which scores can be assigned to genes in the network (this version of the algorithm is called generalizedHotNet - see Vandin et al., PSB 2012).

HotNet version 1.0.0 (July 13th, 2012)
This new version merges the old HotNet and Generalized HotNet methods, requires a new, cleaner representation for copy number aberrations, and adds a number of new features - see the README.txt in archive download for details.
HotNet (ver0.9.1, June 29, 2011)
For finding significantly mutated subnetworks using single nucleotide mutations (and indels) and copy number aberrations (that is, the statistical test performed by HotNet is designed for these types of data).
Generalized HotNet (ver0.9.1, June 29, 2011)
A general version of HotNet that allows for arbitrary gene scores. (The statistical test is a general test that can be used with any score.)
