Methods for Mean Diffusivity in Package `dti'

Compute mean diffusivity (MD) from dtiData or dtiTensor objects

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

Arguments

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
