Annotation channels & event types (실측 / measured)

Sub-database	Channels (typical)	Sampling	Expert events
Spindles	C3-A1 / FP1-A1 / O1-A1 / EOG	100 / 200 Hz	355 spindles
Kcomplexes	CZ-A1 / FP1-A2 / O1-A2	200 Hz	272 K-complexes
REMs	CZ-A1 / EOG1 / EOG2	200 Hz	847 REM eye movements
Artifacts	CZ-A1 / EOG / EMG	50 Hz	2000 artifact events (10 sub-types)
PLMs	CZ-A1 / EMG1-3	200 Hz	4421 PLM events
Apnea	CZ-A1 / NAF / VTH / VAB / SAO2	200 Hz	4058 hypopnea events
Subjects	CZ-A1 / FP1-A2 / O1-A2 / EOG	200 Hz	hypnogram only (5 s epoch)
Patients	CZ-A1 / FP1-A2 / O1-A2 / EOG	200 Hz	hypnogram only (5 s epoch)

Hypnogram conventions

DREAMS uses a 5-second epoch hypnogram (finer than AASM 30-second standard) to align with event-level annotations.

R&K coding:

5 = Wake     4 = REM     3 = N1     2 = N2     1 = N3     0 = N3 (stage 4 merged)     -1 = MT/Unscored

Subjects/Patients additionally provide AASM-coded hypnograms in HypnogramAASM_*.txt.
