Recommendation

We strongly suggest you do NOT use this function in your analysis pipeline to fetch this dataset from openneuro.

The Datalad package offers more flexibility to access those datasets:

Note also that each openneuro dataset has a tab giving you advice on how to download it (see for example).

Parameters:
data_dirpathlib.Path or str or None, optional

Path where data should be downloaded. By default, files are downloaded in a nilearn_data folder in the home directory of the user. See also nilearn.datasets.utils.get_data_dirs.

verbosebool or int, default=1

Verbosity level (0 or False means no message).

Returns:
urls_pathstr

Path to downloaded dataset index.

Sorted list of dataset directories.

Notes

If the dataset files are already present in the user’s Nilearn data directory, this fetcher will not re-download them. To force a fresh download, you can remove the existing dataset folder from your local Nilearn data directory.
