path : str, optional
Path to the directory with the extracted content of the tutorial
data package. This is only necessary for accessing the full resolution
data. The 1slice, and 25mm flavors are shipped with PyMVPA
itself, and the path argument is ignored for them. This function also
honors the MVPA_LOCATION_TUTORIAL_DATA environment variable, and the
respective configuration setting.
roi : str or int or tuple or None, optional
Region Of Interest to be used for masking the dataset. If a string is
given a corresponding mask image from the demo dataset will be used
(mask_<str>.nii.gz). If an int value is given, the corresponding ROI
is determined from the atlas image (mask_hoc.nii.gz). If a tuple is
provided it may contain int values that a processed as explained
before, but the union of a ROIs is taken to produce the final mask.
If None, no masking is performed.
add_fa : dict, optional
Passed on to the dataset creator function (see fmri_dataset() for
more information).
flavor: str, optional :
Resolution flavor of the data to load. By default, the data is loaded in
its original resolution. The PyMVPA source distribution contains a ‘25mm’
flavor that has been downsampled to a very coarse resolution and can be
used for quick test execution. Likewise a 1slice flavor is available
that contents a full-resultion single-slice subset of the dataset.
