object

Determines quantity to estimate, coefficients ot the orientation density function (ODF) (<code>what="ODF"</code>, <code>what="wODF"</code>, <code>what="aODF"</code>)  or the apparent diffusion 
  coefficient (ADC) (<code>what="ADC"</code>) with respect to

what

even integer: maximum order of the sperical harmonics expansion

order

lambda

The method estimates, in each voxel, the coefficients of an expansion of the apparent diffusion cefficient (ADC) with respect to a apherical harmonics  orthonormal system  from the DWI data contained in an object of class <code>"dtiData"</code>.

Diffusion Weighted Imaging (DWI) is a Magnetic Resonance
        Imaging modality, that measures diffusion of water in tissues
        like the human brain. The package contains R-functions to
        process diffusion-weighted data. The functionality includes
        diffusion tensor imaging (DTI), structural adaptive smoothing
        in in case of (DTI) (K. Tabelow, J. Polzehl, V. Spokoiny, and
        H.U. Voss, Diffusion Tensor Imaging: Structural Adaptive
        Smoothing, Neuroimage 39(4), 1763-1773 (2008)), modeling for
        high angular resolution diffusion weighted imaging (HARDI)
        using Q-ball-reconstruction and tensor mixture models and a
        stremaline fiber tracking for tensor and tensor mixture models.
        The package provides functionality to manipulate and visualize
        results in 2D and 3D.
