Stored max-absolute-scaled response
x = (clean signal - mean R0) / abs(mean R0); y = x / max(|x|), per sample and sensor trace
Calculates a signed response from the approved baseline window, then preserves its sign and shape while scaling each trace to the interval [-1, 1].
Use with care: Because each trace is scaled independently, response magnitude cannot be compared between samples or sensor channels.
Imported baseline-normalized
Use the normalized value supplied with the published dataset
Reproduces the source dataset's stored response without recalculating a baseline.
Use with care: The source pipeline and baseline definition may differ between datasets; inspect dataset provenance before comparing values.
Source signal (no normalization)
y = raw or clean signal
Shows the selected source measurement as stored, with no baseline transformation.
Use with care: Absolute sensor levels can differ across channels and arrays, so magnitude alone is not a cross-sensor comparison.
Absolute baseline-relative change
|ΔR/R₀| = |R(t) − R₀| / |R₀|
Reports the size of change from the baseline while ignoring direction.
Use with care: A missing or near-zero baseline cannot produce a stable value.
Signed baseline-relative change
ΔR/R₀ = (R(t) − R₀) / |R₀|
Preserves whether the signal rises or falls relative to the baseline.
Use with care: A missing or near-zero baseline cannot produce a stable value.
Baseline ratio
R(t) / R₀
Expresses each measurement as a multiple of its baseline level.
Use with care: Ratios become unstable when the baseline is close to zero.
Baseline z-score
z = (R(t) − center(R₀)) / sd(R₀)
Expresses change in units of baseline variability for that sensor.
Use with care: Requires at least two variable baseline observations.
