Quickstart#

Get Started

Install

pip install eegdash

Access the data

from eegdash.dataset import DS003516

dataset = DS003516(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Query & Filter

Filter by subject

dataset = DS003516(cache_dir="./data", subject="01")

Advanced query

dataset = DS003516(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

About This Dataset#

Within this experiment 25 participants performed a two-competing speaker paradigm. Participants were instructed to either attend to the left or right audio book. The paradigm consisted of five 10-minute blocks of audio book presentation. In each 10-minute block the participants own name was presented 10 times, embedded within the to-be-ignored audio book. A 10-minute block could either be presented in the omnidirectional condition (both audio books were presented equally loud) or within the beamforming condition (the to-be-attended audio book was louder than the to-be-ignored audio book). The first 10-minute block was always presented in the omnidirectional condition whereas the conditions were alternated for the later four blocks, with one half of the participants starting with the omnidirectonal condition and the other half starting with the beamforming condition. The article (https://doi.org/10.3389/fnins.2021.643705) contains all methodological details

class eegdash.dataset.DS003516(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds003516. Modality: eeg; Experiment type: Attention; Subject type: Healthy. Subjects: 25; recordings: 25; tasks: 1.

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.
