mne.preprocessing.nirs.beer_lambert_law#
- mne.preprocessing.nirs.beer_lambert_law(raw, ppf=6.0, *, sd_distances=None)[source]#
Convert NIRS optical density data to haemoglobin concentration.
- Parameters:
- rawinstance of
Raw The optical density data.
- ppf
tuple|float The partial pathlength factors for each wavelength.
Changed in version 1.7: Support for different factors for the two wavelengths.
- sd_distancesarray_like |
float|None Source-detector distances in meters. If
None, distances are read fromraw.info['chs']. If array-like, the values must have a distance for each channel, matching the order ininfo['chs'].New in v1.13.

- Returns:
- rawinstance of
Raw The modified raw instance.
- rawinstance of
