mne.datasets.sleep_physionet.temazepam.fetch_data(subjects, *, path=None, force_update=False, base_url='', verbose=None)[source]

Get paths to local copies of PhysioNet Polysomnography dataset files.

This will fetch data from the publicly available subjects from PhysioNet’s study of Temazepam effects on sleep 1. This corresponds to a set of 22 subjects. Subjects had mild difficulty falling asleep but were otherwise healthy.

See more details in the physionet website 2.

subjectslist of int

The subjects to use. Can be in the range of 0-21 (inclusive).

pathNone | str

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


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


The base URL to download from.

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.


List of local data paths of the given type.


For example, one could do:

>>> from mne.datasets import sleep_physionet
>>> sleep_physionet.temazepam.fetch_data(subjects=[1]) 

This would download data for subject 0 if it isn’t there already.
