== DTI Analysis: Tensor-based Group Comparison ==

''Objective:'' To boost statistical sensitivity for group comparisons in comparison to 'traditional' univariate tests.

=== Example ===

The figure shows an example of the potential gain in sensitivity using a multivariate tensor test in comparison to the univariate FA test:

'''Status''' The tensor based group comparison method was released into the FreeDiffusion environment at MGH. Paper submitted: "Statistical Group Comparison of Diffusion Tensors via Multivariate Hypothesis Testing." The implementation is in Matlab. Results are able to be visualized in Slicer.
