Notes
Contains the sampled (per streamline) metrics (length, sift2 weights, and mean microstructural properties) for all streamlines. These are also stored in half-precision floating-point format, with multiplicative factors of 1e3 and 1e-3 applied to the mean MD and mean S0 metrics, respectively, to scale the magnitudes of floating-point values toward unity and therefore mitigate loss of precision.
