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'
