This is a software package for processing diffusion tensor imaging data. The following functions are included:
1. Converting imaging data in DICOME format to ANALYZE format
2. Extracting binary brain mask for quick scalp-removing
3. Correcting eddy-current induced distortion
4. Optimized tensor estimation based on noisy diffusion-weighted imaging (DWI) data
5. Scalp removal using a brain mask image
6. Corregistering imaging data and generating deformation field for mapping images from individual spaces to a template or target space
7. Spatial Normalization and Warping DTI
8. Fiber tracking
9. Clustering fiber tracts
10. Identifying brain ventricles and generating binary masks for the baseline and DW imaging data
11. Deriving diffusion anisotropy indices (DAIs) and principal directions (PD) and the corresponding color-coded PD-map.
