EEG motor imagery datasets

Unmodified copies of public EEG motor imagery datasets in the MOABB cache layout. Files extracted from an upstream archive keep their bytes; Weibo2014's also take the names MOABB gives them. Zhou2016's saved Zenodo record is the one generated file; see its section.

Loading

Every dataset loads the same way with MOABB 1.7:

  1. Download the files you need with snapshot_download, narrowed by allow_patterns.
  2. Point MOABB at them through its MNE_DATASETS_<SIGN>_PATH environment variable.
  3. Call moabb.set_download_provider("upstream") so MOABB uses the local files instead of contacting NEMAR.

Each example below loads subject 1. The pattern for all of a dataset's subjects is given in its text.

BNCI2014_001

Each subject's two sessions as MOABB downloads them from BNCI Horizon: A01T.mat (training) and A01E.mat (evaluation) for subject 1, and so on, plus the dataset's description.pdf. MOABB reads every BNCI dataset from MNE_DATASETS_BNCI_PATH. For all 9 subjects, use allow_patterns="BNCI2014_001/*".

import os

from huggingface_hub import snapshot_download

path = snapshot_download("bkowshik/eeg-mi-datasets", repo_type="dataset", allow_patterns="BNCI2014_001/*/A01*")
os.environ["MNE_DATASETS_BNCI_PATH"] = os.path.join(path, "BNCI2014_001")

BNCI2014_002

Each subject's training and evaluation files as MOABB downloads them from BNCI Horizon: S01T.mat and S01E.mat for subject 1, and so on, plus the dataset's description.pdf. MOABB loads both files as one session. MOABB reads every BNCI dataset from MNE_DATASETS_BNCI_PATH, so point it at one BNCI dataset's folder at a time. For all 14 subjects, use allow_patterns="BNCI2014_002/*".

import os

BNCI2015_001

One file per session as MOABB downloads them from BNCI Horizon: S01A.mat and S01B.mat for subject 1, and so on; subjects 8–11 also have S08C.mat to S11C.mat. The dataset's description.pdf comes with them. MOABB reads every BNCI dataset from MNE_DATASETS_BNCI_PATH. For all 12 subjects, use allow_patterns="BNCI2015_001/*".

import os

from huggingface_hub import snapshot_download

path = snapshot_download("bkowshik/eeg-mi-datasets", repo_type="dataset", allow_patterns="BNCI2015_001/*/S01*")

PhysionetMI

All 14 EDF runs of each subject, S001/S001R01.edf to S001/S001R14.edf for subject 1, in the folder where MOABB and MNE's eegbci keep them. These cover both MOABB's default imagery runs and the executed runs (PhysionetMI(executed=True)). The .edf.event files are left out, since the EDF annotations hold the same events. MOABB reads it from MNE_DATASETS_EEGBCI_PATH. For all 109 subjects, use allow_patterns="PhysionetMI/*".

import os

from huggingface_hub import snapshot_download

path = snapshot_download("bkowshik/eeg-mi-datasets", repo_type="dataset", allow_patterns="PhysionetMI/*/S001/*")

moabb.set_download_provider("upstream")
data = Weibo2014(subjects=[1]).get_data()

Yang2025

The two-class part of figshare's single 65.6 GB archive, extracted in the folder where MOABB unpacks it:

  • each session's raw recording (data.bdf) and events (evt.bdf) under sourcedata/2C dataset/sub-<NNN>/;
  • the authors' preprocessed .mat files under derivatives/2C dataset_processeddata/;
  • the release files.

MOABB skips the archive when it finds these files. The three-class part (11 people) and six JPEG images beside the two-class recordings are left out. For all 51 subjects, use allow_patterns="Yang2025/*".

import os

from huggingface_hub import snapshot_download

path = snapshot_download("bkowshik/eeg-mi-datasets", repo_type="dataset", allow_patterns="Yang2025/*/sourcedata/2C dataset/sub-001/*")

Zhou2016

The per-subject zips of MOABB's BIDS copy on Zenodo, each holding a subject's three sessions, plus the BIDS release files and 16534752.json, the Zenodo record MOABB saves and reads offline. That record is the one file not copied byte for byte: it is saved without Zenodo's daily view and download counts, which MOABB never reads. MOABB unpacks each zip beside it on first load, so download into a folder of your own. For all 4 subjects, use allow_patterns="Zhou2016/*".

import os

from huggingface_hub import snapshot_download

# Release files (all names but sub-*.zip) and subject 1.
patterns = ["Zhou2016/*/[!s]*", "Zhou2016/*/sub-1.zip"]

moabb.set_download_provider("upstream")
data = Zhou2016(subjects=[1]).get_data()

Zhou2020

The per-subject zips MOABB downloads from Zenodo, each holding all seven of a subject's sessions. MOABB unpacks each zip beside it on first load, so download into a folder of your own. For all 20 subjects, use allow_patterns="Zhou2020/*".

import os

from huggingface_hub import snapshot_download

path = snapshot_download("bkowshik/eeg-mi-datasets", repo_type="dataset", allow_patterns="Zhou2020/*/S01.zip", local_dir="eeg-mi-datasets")
