Project description

netsci

Analyzing Complex Networks with Python

Author Version Demo
Gialdetti PyPI Binder

netsci is a python package for efficient statistical analysis of spatially-embedded networks. In addition, it offers efficient implementations of motif counting algorithms. For other models and metrics, we highly recommend using existing and richer tools. Noteworthy packages are the magnificent NetworkX, graph-tool or Brain Connectivity Toolbox.

Installing

Install and update using pip:

$ pip install netsci

A simple example

Analyzing a star network (of four nodes)

>>> import numpy as np
>>> import netsci.visualization as nsv
>>> A = np.array([[0,1,1,1], [0,0,0,0], [0,0,0,0], [0,0,0,0]])
>>> nsv.plot_directed_network(A, pos=[[0,0],[-1,1],[1,1],[0,-np.sqrt(2)]])

Alt text

>>> import netsci.metrics.motifs as nsm
>>> f = nsm.motifs(A, algorithm='brute-force')
>>> print(f)
[1 0 0 0 0 3 0 0 0 0 0 0 0 0 0 0]
>>> nsv.bar_motifs(f)

Testing

After installation, you can launch the test suite:

$ pytest
