<h3>Objective</h3>
We focus on enabling the use of advanced DTI processing within NA-MIC and on automatizing steps to perform [[Projects:AtlasBasedDTIFiberAnalyzerFramework|atlas-based DTI population analysis]]. One component is pair-wise DTI registration which can be directly performed by DTI-Reg, a C++ application developed in that regard.

<h3>Approach, Plan</h3>

DTI-Reg is an open-source C++ application that performs pair-wise DTI registration.
Individual steps of the pair-wise registration pipeline are performed via external applications, called via BatchMake. Starting with two input DTI images, scalar FA maps are generated via dtiprocess. Registration is then performed between these FA maps, via BRAINSFit or BRAINSDemonWarp, which provide different registration schemes: rigid, affine, BSpline, diffeomorphic, logDemons. The final deformation is then applied to the source DTI image via resampleDTI.
