NAME

       ANTSIntegrateVectorField - part of ANTS registration suite

SYNOPSIS

       ANTSIntegrateVectorField       VecImageIN.nii.gz       ROIMaskIN.nii.gz      FibersOUT.vtk
       LengthImageOUT.nii.gz

DESCRIPTION

              The vector field should have vectors as voxels ,  the  ROI  is  an  integer  image,
              fibers out will be vtk text files ....

              ROI-Mask controls where the integration is performed and the start point region ...

              e.g.  the  brain  will  have value 1 , the ROI has value 2 , then all starting seed
              points for the integration will start in the region labeled 2 and be constrained to
              the region labeled 1.
