Blue Brain SNAP

Blue Brain Simulation and Neural network Analysis Productivity layer (Blue Brain SNAP).

Blue Brain SNAP is a Python library for accessing BlueBrain circuit models represented in SONATA <https://github.com/AllenInstitute/sonata/blob/master/docs/SONATA_DEVELOPER_GUIDE.md>__ format.

Installation

Blue Brain SNAP can be installed using pip::

pip install bluepysnap

Usage

There are two main interface classes provided by Blue Brain SNAP:

|circuit| corresponds to the static structure of a neural network, that is:

• node positions and properties,
• edge positions and properties, and,
• detailed morphologies.

|simulation| corresponds to the dynamic data for a neural network simulation, including:

• spike reports,
• soma reports, and,
• compartment reports.

Most of Blue Brain SNAP methods return pandas <https://pandas.pydata.org>__ Series or DataFrames, indexed in a way to facilitate combining data from different sources (that is, by node or edge IDs).

Among other dependencies, Blue Brain SNAP relies on Blue Brain Project provided libraries:

• libsonata <https://github.com/BlueBrain/libsonata>__, for accessing SONATA files
• NeuroM <https://github.com/BlueBrain/NeuroM>__, for accessing detailed morphologies

Tools

Blue Brain SNAP also provides a SONATA circuit validator for verifying circuits.

The validation includes:

• integrity of the circuit config file.
• existence of the different node/edges files and components directories.
• presence of the "sonata required" field for node/edges files.
• the correctness of the edge to node population/ids bindings.
• existence of the morphology files for the nodes.

This functionality is provided by either the cli function:

.. code-block:: shell

bluepysnap validate my/circuit/path/circuit_config.json

Or a python free function:

.. code-block:: python3

from bluepysnap.circuit_validation import validate
errors = validate("my/circuit/path/circuit_config.json")
