Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import NM000272

dataset = NM000272(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = NM000272(cache_dir="./data", subject="01")

Advanced query

dataset = NM000272(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

class eegdash.dataset.NM000272(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

romani-bf2025-erp - NEMAR Dataset

Study:

nm000272 (NeMAR)

Author (year):

Romani2025_BF_ERP

Canonical:

Romani2025_erp

Also importable as: NM000272, Romani2025_BF_ERP, Romani2025_erp.

Modality: eeg; Experiment type: Attention; Subject type: Unknown. Subjects: 22; recordings: 1022; tasks: 3.

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.
