This program implements the variationnal EM algorithm for directed and undirected networks.

mixnet -q <int> -Q <int> <filename.spm> [options]

Main options are:

• - -undirected : Specifies that the network is undirected
• - -improve : Performs improvements of unsatisfying models

For a complete options list:

mixnet -h man mixnet

MixNet provides two Perl programs:

• mixnet-cl c From a MixNet .model file, displays the class of each nodel and creates file for Cytoscape
• mixnet-sim From a MixNet .model file, simulate a network

• Implemented algorithms

• A few lines to discover mixnet
