MCL algorithm

This module implements the Markov Cluster algorithm created by Stijn van Dongen and described in http://www.library.uu.nl/digiarchief/dip/diss/1895620/inhoud.htm.

This implementation is still in beta and is not yet optimized for large networks.

##Installation

python setup.py install

##Usage

###Command line

Usage: mcl_clustering.py [options] <input_matrix>

Options
  -h, --help            show this help message and exit
  -e EXPAND_FACTOR, --expand_factor=EXPAND_FACTOR
                        expand factor (default: 2)
  -i INFLATE_FACTOR, --inflate_factor=INFLATE_FACTOR
                        inflate factor (default: 2)
  -m MULT_FACTOR, --mult_factor=MULT_FACTOR
                        multiply factor (default: 2)
  -l MAX_LOOP, --max_loops=MAX_LOOP
                        max loops (default: 60)
  -o FILE, --output=FILE
                        output (default: stdout)
  -v, --verbose         verbose (default: True)
  -d, --draw-graph      show graph with networkx (default: False)

The input matrix must be as comma-separated value file representing the adjacency matrix.

An example is the file example.csv in examples dir.

try: mcl_clustering.py -d -e 3 <example_path>/example.csv

###Code

####Using numpy adjacency matrix

from mcl_clustering import mcl

A = <your matrix>

M, clusters = mcl(A, expand_factor = <expand_factor>,
                   inflate_factor = <inflate_factor>,
                   max_loop = <max_loop>,
                   mult_factor = <mult_factor>)

####Using a networkx graph

from mcl_clustering import networkx_mcl

G = <your graph>

M, clusters = networkx_mcl(G, expand_factor = <expand_factor>,
                   inflate_factor = <inflate_factor>,
                   max_loop = <max_loop>,
                   mult_factor = <mult_factor>)


Output
    M = otuput matrix
    clusters = dict with keys = [<cluster id>] values = [<vertex id>]
