an object of class <code>"dtiData"</code>

object

S0 intensity value to be used to discriminate between
       voxel inside and outside the brain. A good value of level may be determined
       using method <code>sdpar</code> in advance.

level

proportion of voxel in test area with s0 value larger than level
    needed to decide for a voxel inside the brain

prop

size

Create a mask containing voxel inside the head

methods

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.
