• Change save free water to --recordFreeWater

    --recordFreeWater
     Record output from tensor plus free water model: Save the fraction of
     free water. Attaches field 'FreeWater' to fiber. (value: 0)

   --freeWater
     Adds a term for free water diffusion to the model. The free water
     model is a tensor with all 3 eigenvalues equal to the diffusivity of
     free water (0.003). To output the free water fraction, make sure to
     use the 'save free water' parameter. (value: 0)
