mne.datasets.eegbci.load_data

mne.datasets.eegbci.load_data(subject, runs, path=None, force_update=False, update_path=None, base_url='https://physionet.org/files/eegmmidb/1.0.0/', verbose=None)[source]

Get paths to local copies of EEGBCI dataset files.

This will fetch data for the EEGBCI dataset 1, which is also available at PhysioNet 2.

Parameters
subjectint

The subject to use. Can be in the range of 1-109 (inclusive).

runsint | list of int

The runs to use. See Notes for details.

pathNone | str

Location of where to look for the EEGBCI data storing location. If None, the environment variable or config parameter MNE_DATASETS_EEGBCI_PATH is used. If it doesn’t exist, the “~/mne_data” directory is used. If the EEGBCI dataset is not found under the given path, the data will be automatically downloaded to the specified folder.

force_updatebool

Force update of the dataset even if a local copy exists.

update_pathbool | None

If True, set the MNE_DATASETS_EEGBCI_PATH in mne-python config to the given path. If None, the user is prompted.

base_urlstr

The URL root for the data.

verbosebool | str | int | None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

Returns
pathslist

List of local data paths of the given type.

Notes

The run numbers correspond to:

run

task

1

Baseline, eyes open

2

Baseline, eyes closed

3, 7, 11

Motor execution: left vs right hand

4, 8, 12

Motor imagery: left vs right hand

5, 9, 13

Motor execution: hands vs feet

6, 10, 14

Motor imagery: hands vs feet

For example, one could do:

>>> from mne.datasets import eegbci
>>> eegbci.load_data(1, [4, 10, 14], os.getenv('HOME') + '/datasets') 

This would download runs 4, 10, and 14 (hand/foot motor imagery) runs from subject 1 in the EEGBCI dataset to the ‘datasets’ folder, and prompt the user to save the ‘datasets’ path to the mne-python config, if it isn’t there already.
