Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS006914

dataset = DS006914(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS006914(cache_dir="./data", subject="01")

Advanced query

dataset = DS006914(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

About This Dataset#

This dataset, used in the analysis reported by Kochi et al., (2025), contains intracranial EEG recordings from 110 individuals who performed an visual‑naming task. Electrode coordinates are provided in MNI‑305 space.

Each EDF file is tagged for the visual naming task with the following event codes: 401 – stimulus onset 501 – response onset

API Reference#

Use the DS006914 class to access this dataset programmatically.

class eegdash.dataset.DS006914(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds006914. Modality: ieeg; Experiment type: Other; Subject type: Epilepsy. Subjects: 110; recordings: 353; 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.
