IXI Aging DTI Template

- Content of the distribution

1) The "template" directory contains

a) the IXI aging template in NIfTI tensor volume format with the number of voxels in each dimension 128x128x64 and the physical dimension of each voxel 1.75x1.75x2.25 mm^3.

b) the brain area mask corresponding to the IXI aging template in 1).

2) The "tsa" directory contains the individually annotated white matter tracts. For each tract, the annotation includes

a) the binary segmentation in the root directory of each tract

b) the surface models of different resolutions and their associated boundary models in the "fitting/mesh" directory

c) the very coarse surface models for initializing shape-based normalization in the "fitting/cmrep" directory

3) The "ixi_license" directory contains

the license agreement pertaining to the use of IXI brain database.

4) The "citation" directory contains

the manuscript describing the construction of the template.
