============================
Read and plot coregistration
============================

We'll take a look at the coregistration here.



.. code-block:: python

    import os.path as op

    from hcp.viz import plot_coregistration







we assume our data is inside a designated folder under $HOME



.. code-block:: python

    storage_dir = op.expanduser('~/mne-hcp-data')







and we assume to have the downloaded data, the MNE/freesurfer style
anatomy directory, and the MNE style MEG directory.
these can be obtained from :func:`make_mne_anatomy`.
See also :ref:`tut_make_anatomy`.



.. code-block:: python


    hcp_params = dict(
        subject='105923',
        hcp_path=op.join(storage_dir, 'HCP'),
        subjects_dir=op.join(storage_dir, 'subjects'),
        recordings_path=op.join(storage_dir, 'hcp-meg'))







let's plot two views



.. code-block:: python


    for azim in (0, 90):
        plot_coregistration(
            view_init=(('azim', azim), ('elev', 0)), **hcp_params)
