Quickstart#

Install

pip install eegdash

raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS008711(cache_dir="./data", subject="01")

Advanced query

dataset = DS008711(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

About This Dataset#

Data collection took place at the NeuroCognition Laboratory (NCL) in San Diego, California under the supervision of Dr. Phillip Holcomb. This project followed the San Diego State University’s IRB guidelines.

Participants sat in a comfortable chair in a darkened sound attenuated room throughout the experiment. They were given a keyboard for button pressing and wore a lightweight headset to record their verbal responses. They were instructed to watch the LCD video monitor that was at a viewing distance of 60 in (152 cm).

Participants were presented with 180 sentences, the critical center word was presented in white New Courier font on a black background, while the flanker words on each side of the critical word were presented in a grey New Courier font. Words ranged from 1 - 14 letters long and sentences ranged from 6 – 12 words long. Words were presented with a height of 80 and width of 40, the fovea visual angle ranged from .75 – 6.21 degrees, with the largest peripheral visual angle of 15.18 degrees. Conditions consisted of 30 subject-verb agreement violations, 30 semantic violations, 30 double (subject-verb agreement + semantic) violations, 30 word-order violations, and 60 control (correct) sentences. Sentences were presented in an RSVP with flankers design, with three words presented at a time in the middle of the screen, each word appeared in the middle of the screen for a duration of 400ms before appearing to slide to the right and be replaced by the next word in the sentence. There was no ISI for this task to eliminate the words from appearing to flash at the participant instead of sliding.

NEMAR Processing Statistics#

The plots below are generated by NEMAR’s automated EEG pipeline. The histogram shows pipeline success for data cleaning and ICA decomposition, the percentage of data frames and EEG channels retained after artefact removal, line noise per channel (RMS, dB), and the age/gender distribution of participants.

Also importable as: DS008711.

Modality: eeg; Subject type: Unknown. Subjects: 64; recordings: 64; 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.

Examples

>>> from eegdash.dataset import DS008711
>>> dataset = DS008711(cache_dir="./data")
>>> recording = dataset[0]
>>> raw = recording.load()
__init__(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#
save(path: str, overwrite: bool = False, offset: int = 0)[source]#

Save datasets to files by creating one subdirectory for each dataset:

path/
    0/
        0-raw.fif | 0-epo.fif
        description.json
        raw_preproc_kwargs.json (if raws were preprocessed)
        window_kwargs.json (if this is a windowed dataset)
        window_preproc_kwargs.json  (if windows were preprocessed)
        target_name.json (if target_name is not None and dataset is raw)
    1/
        1-raw.fif | 1-epo.fif
        description.json
        raw_preproc_kwargs.json (if raws were preprocessed)
        window_kwargs.json (if this is a windowed dataset)
        window_preproc_kwargs.json  (if windows were preprocessed)
        target_name.json (if target_name is not None and dataset is raw)
Parameters:
  • path (str) –

    Directory in which subdirectories are created to store

    -raw.fif | -epo.fif and .json files to.

  • overwrite (bool) – Whether to delete old subdirectories that will be saved to in this call.

  • offset (int) – If provided, the integer is added to the id of the dataset in the concat. This is useful in the setting of very large datasets, where one dataset has to be processed and saved at a time to account for its original position.
