EESM23-Processed
Preprocessed HDF5 export of the EESM23 (Aarhus in-ear EEG sleep) BIDS
dataset — 10 subjects, 2 nights each (ses-001, ses-002), one 30-second
AASM scoring epoch per row (Wake / N1 / N2 / N3 / REM; Artefact
epochs dropped). sub-006/ses-002 PSG is skipped — the source .set file is
truncated on disk.
Preprocessing
Only a 0.1–100 Hz band-pass + 50 Hz notch filter is applied, on the full
continuous recording before slicing into 30 s epochs (to avoid per-epoch
filter edge effects). Nothing else: no re-referencing, no resampling, no
channel renaming. Channel names are kept exactly as in the source BIDS
channels.tsv.
Device data-loss gaps (NaN samples) are linearly interpolated before
filtering (a long FIR kernel otherwise smears each NaN across a wide window)
and the true NaN positions are restored afterward, so nan_fraction still
reflects genuine data quality rather than a filtering artifact.
Generated by dataset/preprocess_eesm23.py in the EEGFM repo.
