Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS003655

dataset = DS003655(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS003655(cache_dir="./data", subject="01")

Advanced query

dataset = DS003655(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

About This Dataset#

raw EEG in a modified Sternberg working memory paradigm with two types of task: with mental manipulations (alphabetization) and simple retention (TASK) and 3 levels of load: 5, 6, or 7 letter to memorize (LOAD).

Events.tsv files in eeg folders contain event descriptions (see column trial_type).

trial_type = {

‘500’ ‘start of the trial’; ‘150’ ‘start of the baseline period: Retention of 5 letters (5R)’; ‘151’ ‘start of the baseline period: Manipulation with 5 letters (5M)’; ‘160’ ‘start of the baseline period: Retention of 6 letters (6R)’; ‘161’ ‘start of the baseline period: Manipulation with 6 letters (6M)’;

API Reference#

Use the DS003655 class to access this dataset programmatically.

class eegdash.dataset.DS003655(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds003655. Modality: eeg; Experiment type: Memory; Subject type: Healthy. Subjects: 156; recordings: 156; 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.
