NNGT: a unified interface for networks in python
The Neural Networks and Graphs' Topology (NNGT) module provides tools to generate and study graphs and detailed biological networks. It also lets user interface efficient graph libraries with highly distributed activity simulators to make the study of neuronal activity as easy and efficient as possible.
Source code is available and contributions are accepted on SourceHut (preferred), Codeberg, and GitHub.
For questions or issues, please check the mailing list and the issue tracker.
NNGT provides a unified interface that acts as a wrapper for 3 major graph libraries in Python: networkx, igraph, and graph-tool.
Use the same code, run it at home on the latest linux with graph-tool, then on your collaborator's laptop with networkx on Windows, no changes required!
In addition to this common interface, NNGT provides additional tools and methods to generate complex neuronal networks. Once the networks are created, they can be seamlessly sent to the nest-simulator, which will generate activity. This activity can then be analyzed together with the structure using NNGT.
Eventually, NNGT is also able to import neuronal networks generated using the DeNSE simulator for neuronal growth.
Install and use the library
NNGT requires Python 3.5+ since version 2.0, and is directly available on Pypi. To install it, make sure you have a valid Python installation, then do:
pip install nngt
If you want to use it with advanced geometry, geospatial or other tools, you can use the various extra to automatically download the relevant dependencies keep only one of the listed possibilities)
pip install nngt[matplotlib|nx|ig|geometry|geospatial]
To install all dependencies, use
pip install nngt[full].
To use it, once installed, open a Python terminal or script file and type
If you want to have the latest updates before they are released into a stable
version, you can install directly from
pip install --user git+https://git.sr.ht/~tfardet/NNGT@main
