SubtractDarkIntensity

Subtract dark intensity channels from intensity channels.

If the data have dark intensity channels, this will subtract those channels' activity from the regular NIRS intensity measures and optionally remove the dark intensity channels from the data (default=True). This node assumes that dark channels have positions set, but positions_source is set to NaN. Alternatively, the dark intensity channels can be passed into the 'dark' data port. Version 1.0.0
