Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS003421

dataset = DS003421(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS003421(cache_dir="./data", subject="01")

Advanced query

dataset = DS003421(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

Dataset 2

Presentation

This dataset was collected between 2014 and 2017 in Rennes (France) during four conditions (resting state, visual naming, auditory naming and working memory tasks). All participants provided a written informed consent to participate in this study which was approved by an independent ethics committee and authorized by the IRB “Comite de Protection des Personnes dans la Recherche Biomedicale Ouest V” (CCPPRB-Ouest V). The study name was “Braingraph” and study agreement number was 2014-A01461-46. Its promoter was the Rennes University Hospital.

Participants

Twenty right-handed healthy volunteers (10 females, 10 males, mean age 23 years) participated in this experiment. (See participants.json and participants.tsv for more details)

Experiment

  • The experiment begins with the verification of inclusion/exclusion criteria.

  • The participants read the information notice and the consent form.

  • Then they sign two questionnaires.

  • One subject –>four conditions (resting state, visual naming, auditory naming and working memory).

  • Resting state–> subject asked to relax for 10 min with their eyes open.

  • Visual naming–>subject asked to name 80 pictures. 40 scrambled pictures were presented and participantس were asked to say nothing.

  • Auditory naming–> subject asked to name 80 different sounds.

  • Memory–> 80 pictures were displayed of which 40 have already been shown in the naming task. New pictures and already seen pictures randomly appeared on the screen and participants have to indicate if they have seen them before by pressing a button or not.

EEG acquisition

  • HD-EEG system (EGI, Electrical Geodesic Inc., 256 electrodes)

  • Sampling frequency: 1000Hz

  • Impedances were kept below 5k

API Reference#

Use the DS003421 class to access this dataset programmatically.

class eegdash.dataset.DS003421(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds003421. Modality: eeg; Experiment type: Decision-making; Subject type: Healthy. Subjects: 20; recordings: 80; 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.
