Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS004348

dataset = DS004348(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS004348(cache_dir="./data", subject="01")

Advanced query

dataset = DS004348(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

for rec in dataset:
    print(rec.subject, rec.raw.info['sfreq'])

About This Dataset#

Ear-EEG Sleep Monitoring 2017 (EESM17) data set

Overview

This dataset was collected as part of a research project on ear-EEG sleep monitoring which took place in 2017.

The data set contains nightly EEG recordings from 9 healthy participants (‘subjects’). The recordings consist of ‘partial polysomnography’ (PSG) measurements, including EEG, EOG and chin EMG combined with 14 ear-EEG electrodes.

Ear-EEG Sleep Monitoring 2017 (EESM17) data set

Overview

This dataset was collected as part of a research project on ear-EEG sleep monitoring which took place in 2017.

The data set contains nightly EEG recordings from 9 healthy participants (‘subjects’). The recordings consist of ‘partial polysomnography’ (PSG) measurements, including EEG, EOG and chin EMG combined with 14 ear-EEG electrodes.

Format

The dataset is formatted according to the Brain Imaging Data Structure. See the ‘dataset_description.json’ file for the specific BIDS version used. The EEG data format chosen is the ‘.set’ format of EEGLAB.

For more information, see the following link: https://bids-specification.readthedocs.io/en/stable/01-introduction.html

Task description

The subjects were instructed to perform two recordings. In the first recording, they had to simply relax in a chair either reading or watching television, prior to going to bed. These recordings are labeled as ‘wake’ task. After this, the real recording started, which took place during the night and began when the subject went to bed. These recordings are labeled as having task ‘sleep’. The recording equipment was mounted in the afternoon, and the recordings took place at the subject’s home.

The data set was previously described in the paper: https://doi.org/10.1186/s12938-017-0400-5 When citing this data set, please refer to this paper.

Please note that for all subjects, the sleep scoring begins at ‘Lights out’.

Notes

Due to a miscommunication in the original sleep study, two ear-EEG channels, ERB1 and ELB1, were not used. However, they are included in the data set. Both electrode positions were very close to the ERB and ELB positions.

API Reference#

Use the DS004348 class to access this dataset programmatically.

class eegdash.dataset.DS004348(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds004348. Modality: eeg; Experiment type: Sleep; Subject type: Healthy. Subjects: 9; recordings: 18; tasks: 2.

Parameters:

  • cache_dir (str | Path) – Directory where data are cached locally.

  • query (dict | None) – Additional MongoDB-style filters to AND with the dataset selection. Must not contain the key dataset.

  • s3_bucket (str | None) – Base S3 bucket used to locate the data.

  • **kwargs (dict) – Additional keyword arguments forwarded to EEGDashDataset.

data_dir#

Local dataset cache directory (cache_dir / dataset_id).

Type:

Path

query#

Merged query with the dataset filter applied.

Type:

dict

records#

Metadata records used to build the dataset, if pre-fetched.

Type:

list[dict] | None

Notes

Each item is a recording; recording-level metadata are available via dataset.description. query supports MongoDB-style filters on fields in ALLOWED_QUERY_FIELDS and is combined with the dataset filter. Dataset-specific caveats are not provided in the summary metadata.
