Methods for Mean Diffusivity in Package ‘dti’

Compute mean diffusivity (MD) from dtiData or dtiTensor objects

  ## S4 method for signature 'dtiData'
dwiMD(object, eps=.05)
  ## S4 method for signature 'dtiTensor'
dwiMD(object)

`object`	Object of class `"dtiData"` or `"dtiTensor"`
`eps`	tolerance in search for good gradient combinations.

Array of mean diffusivities.

signature(object = "ANY"): Returns a warning
signature(object = "dtiData"): searches for three gradients that enable best MD evaluation. Returns MD.
signature(object = "dtiTensor"): calculates MD values from estimated difusion tensors
