Tensor : Compute DTI Contrasts 1.10 RC (Tensor_Compute_DTI_Contrasts)

IACL.DTI.Contrasts

[edu.jhu.ece.iacl.plugins.dti.DWITensorContrasts]

Description

Estimates tensor contrasts.

Notes

Estimates tensor contrasts.By default, estimates Mean Diffusion (MD), Fractional Anisotropy (FA), and the primary eigenvector (VEC1). Can optionally output all eigenvalues/vectors, as well as Relative Anisotropy (RA), and Volume Ratio (VR).
Note that this module takes a 4-D volume as input, while most Tensor Estimators have a file as output. Use the 'FileCollection to VolumeCollection' module to convert.
