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),
             diffusion kurtosis imaging (DKI), modeling for high angular resolution 
             diffusion weighted imaging (HARDI) using Q-ball-reconstruction and 
             tensor mixture models, several methods for structural adaptive 
             smoothing including POAS and msPOAS, and a streamline fiber tracking 
             for tensor and tensor mixture models.
             The package provides functionality to manipulate and visualize results 
             in 2D and 3D.
