Overview
========

The Neural Network Growth and Topology (NNGT) module provides tools to grow and
study detailed biological networks by interfacing efficient graph libraries
with highly distributed activity simulators.

The library has two main targets:

* people looking for a unifying interface for the three main graph library,
  allowing to run and share a single code on different platforms
* neuroscience people looking for an easy way to generate complex networks
  while keeping track of neuronal populations and their biological properties


Main classes
------------

NNGT provides four main classes, the two first being aimed at the
graph-theoretical community, the third and fourth are more for the neuroscience
community:

:class:`~nngt.Graph`
  provides a simple implementation over graphs objects from graph libraries
  (namely the addition of a name, management of detailed nodes and connection
  properties, and simple access to basic graph measurements).
:class:`~nngt.SpatialGraph`
  a Graph embedded in space (nodes have positions and connections are
  associated to a distance)
:class:`~nngt.Network`
  provides more detailed characteristics to emulate biological neural
  networks, such as classes of inhibitory and excitatory neurons, synaptic
  properties...
:class:`~nngt.SpatialNetwork`
  combines spatial embedding and biological properties


Generation of graphs
--------------------

Structured connectivity:
  connectivity between the nodes can be chosen from various well-known graph
  models
Populations:
  populations of neurons are distributed afterwards on the structured
  connectivity, and can be set to respect various constraints (for instance a
  given fraction of inhibitory neurons and synapses)
Synaptic properties:
  synaptic weights and delays can be set from various distributions or
  correlated to edge properties


Interacting with NEST
---------------------

The generated graphs can be used to easily create complex networks using the
NEST simulator, on which you can then simulate their activity.
