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.
|build_status| |coverage|
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 filesNeuroM <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
componentsdirectories. - 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")
