Similar to what is reported in the link, could we run waveform analysis to get things like:
Area under the curve (AUC): Integral of the HbO/HbR signal over a specified time window. Captures both amplitude and duration of the response.
Cumulative HbO / HbR response: Sometimes reported as total oxygenation or "oxygenation index" (HbO – HbR).
Time-to-peak (TTP): Time from stimulus onset to maximum HbO (or minimum HbR).
Full-width at half-maximum (FWHM): Duration the response stays above half its peak.
Slope: Rate of increase in HbO during the rising phase.
Recovery slope: Rate of return to baseline after peak.
Onset latency: When the signal first rises significantly above baseline.

From my reading we want the two MNE documentations BUT the actual calculations we may have to get from source papers.
