Visualizing Megatrawls Network Matrices from Human Connectome Project
=====================================================================

This example shows how to fetch network matrices data from HCP beta-release
of the Functional Connectivity Megatrawl project.

See :func:`nilearn.datasets.fetch_megatrawls_netmats`
documentation for more details.

Fetching the Megatrawls Network matrices
----------------------------------------
Fetching the partial correlation matrices of dimensionality d=300 with
timeseries method 'eigen regression'

.. GENERATED FROM PYTHON SOURCE LINES 17-28

.. code-block:: Python

    from nilearn import datasets

    netmats = datasets.fetch_megatrawls_netmats(
        dimensionality=300,
        timeseries="eigen_regression",
        matrices="partial_correlation",
    )
    # Partial correlation matrices array of size (300, 300) are stored in the name
    # of 'correlation_matrices'
    partial_correlation = netmats.correlation_matrices
