eegdash 0.8.3

EEG-DaSh: an open data, tool, and compute resource — a Python library and catalog for 700+ BIDS-first EEG, MEG, fNIRS, EMG, and iEEG datasets, ML-ready via PyTorch

EEG-Dash

EEG-DaSh is a data-sharing archive for MEEG (EEG, MEG) recordings contributed by collaborating labs. It preserves publicly funded research data and exposes it in a form that machine learning and deep learning workflows can use directly.

Data source

The archive draws on 25 labs and 27,053 participants, with recordings covering both EEG and MEG. Subjects include healthy controls and clinical groups: ADHD, depression, schizophrenia, dementia, autism, and psychosis. Tasks range across sleep, meditation, and cognitive paradigms. EEG-DaSh also pulls in 330 BIDS-formatted MEEG datasets converted from NEMAR.

Data format

EEGDash queries return a PyTorch Dataset. The format plugs directly into PyTorch's DataLoader for batching, shuffling, and parallel loading, which matters when training models on large EEG corpora.

Data preprocessing

EEGDash datasets are braindecode datasets, which are themselves PyTorch datasets. Any preprocessing that works on a braindecode dataset works on an EEGDash dataset. See the braindecode tutorials for the available options.

EEG-Dash usage

Install

Requires Python 3.10 or higher. Use whichever environment manager you prefer.

pip install eegdash

Verify the install in a Python session:

from eegdash import EEGDash

See the tutorials at eegdash.org for end-to-end examples.
