Progress and Roadmap

The data on this page is as of 2026-10-11.

Where we are

Datasets at each step, from converted to out of reach.

1. 66v0 converted45,549 h
2. 11v1 to convert+970 h measured; SparrKULee unmeasured
3. 1to ingestSiena Scalp EEG Database
4. 8blocked (licence)NoDerivatives or no licence
5. 3gatedTUH EEG Corpus (TUEG), HMS Harmful Brain Activity Classification, TDBRAIN Dataset

66 datasets converted, 11 ingested and waiting for conversion, 1 still to ingest; 8 are blocked by their licence and 3 are gated.

What’s next

1. Host the converted Zarr store eegdash-corpus-v0 (66 datasets, 45,549 h) through EEGDash
2. One conversion pass for v1: the 11 datasets ingested but not converted (970 h measured so far)
3. Deposit the datasets still to ingest (Siena Scalp EEG Database) on NEMAR so EEGDash serves them
4. Multi-dataset download in EEGDash: one call fetches a list of dataset ids

As of 2026-10-11, the date of the data on this page; in order of what comes next.

From REVE’s paper to the versions

REVE’s paper names 89 datasets and its release card 70 entries (93 tracked in all); version 0 converts 66 of them, version 1 adds 12.

66 of the release card's 70 entries are converted (45,549 h); v1 adds 12 more (970 h), and 1 open dataset waits to be ingested.
