Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS007477

dataset = DS007477(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS007477(cache_dir="./data", subject="01")

Advanced query

dataset = DS007477(
    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 was converted from TimeSeriesHbORT_18sub_twoSessionICAdenoise(1).mat using convert_mat_to_bids.py. Notes: - Review and confirm *_nirs.json (SamplingFrequency, NIRSChannelCount, source/detector mapping) before public release. - This README is a placeholder to satisfy BIDS recommendations; replace with dataset-specific information as needed.

Also importable as: DS007477, Niu2026.

Modality: fnirs; Experiment type: Unknown; Subject type: Unknown. Subjects: 18; recordings: 36; 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.
