mne.datasets.erp_core.data_path#

mne.datasets.erp_core.data_path(path=None, force_update=False, update_path=True, download=True, *, verbose=None)[source]#

Get path to local copy of erp_core dataset.

Parameters:

pathNone | str: Location of where to look for the erp_core dataset. If None, the environment variable or config parameter MNE_DATASETS_ERP_CORE_PATH is used. If it doesn’t exist, the “~/mne_data” directory is used. If the erp_core dataset is not found under the given path, the data will be automatically downloaded to the specified folder.
force_updatebool: Force update of the erp_core dataset even if a local copy exists. Default is False.
update_pathbool | None: If True (default), set the MNE_DATASETS_ERP_CORE_PATH in mne-python config to the given path. If None, the user is prompted.
downloadbool: If False and the erp_core dataset has not been downloaded yet, it will not be downloaded and the path will be returned as ‘’ (empty string). This is mostly used for debugging purposes and can be safely ignored by most users.
verbosebool | str | int | None: Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns:
