Wearanize Plus (Wearanize+)

Wearanize+ is a research project in which multiple wearable devices were used to record participants' overnight sleep. The resultant dataset contains raw data from three wearable devices (Zmax, Empatica E4, and ActivPAL) along with parallel polysomnography (SOMNOScreen plus) from 130 participants. The project was carried out at the Donders Centre for Cognitive Neuroimaging, Radboud University, Nijmegen, The Netherlands, by the members of Donders Sleep & Memory Lab.

Overview

This repository contains scripts to preprocess the raw data and perform preliminary analysis on the Wearanize+ dataset v1.0. For more details on the project, see Wearanize+ Dataset v1.0 Publication

Accessing the Dataset

The Wearanize+ dataset is publicly available on the Radboud Repository.
To access the data, please open an ORCID account and follow these instructions. Please see the FAQ section to solve common issues. The published dataset version is titled Wearanize+_v1.0.zip, and the synchronized version is titled Wearanize+_PlugNPlay_v1.0.zip. If you still have trouble accessing the dataset (or have questions), please contact Niloy Sikder at niloy.sikder@donders.ru.nl, mentioning your ORCID ID.

Dataset Contents (PlugNPlay)

Column descriptions:

1. 'SubjectID': Unique identifier for the subject.
2. 'Device': Name of the recording device. (Devices: Zmax, PSG, Empatica, ActivPAL; keys: Zmax, PSG, Emp, Activpal).
3. 'NumOfSignals': Number of signals recorded in 'SignalData'.
4. 'SignalLabel': List of signal names recorded by the device. Example: 'EEGL', 'EEGR', 'ACCX', etc..
5. 'SignalStartDateTime': Start date and time of each signal's recording (%Y-%m-%d %H:%M:%S). Usually the same for all signals of a device. For Zmax and Mentalab, the start times are unreliable.
6. 'SamplingRate': Sampling rate of each signal.
7. 'SignalDurationSec': Duration of each signal in seconds.
8. 'SignalLength': Length of each signal in data points.
9. 'SignalMin': Minimum value of signals associated signal.
10. 'SignalMax': Maximum value of signals associated signal.
11. 'SignalType': Signal modalities (e.g., EEG, EMG).
12. 'SignalUnit': Signal measurement unit.
13. 'SignalData': Actual recorded data for each signal.
14. 'SleepScoreEpochs': Number of 30-second epochs in associated sleep scores.
15. 'SleepScores': Available sleep scores identified from the associated device's data.
