DTI data post-processing

[KMountris]

Hi,

I use the module to generate a DTI volume which I want to process later in Matlab to find the diffusion tensor principal direction by solving the eigen problem for each individual tensor for each voxel.

The tensor is stored in each voxel as a 6-component vector. Could you verify me that the components of the vector correspond to Dxx, Dyy, Dzz, Dxy, Dyz, Dzx? Is this the correct order of the stored data?

Thank you in advance.

Best, Konstantinos

Hi did you save the tensor to disk in nrrd format? That standard is described here: http://teem.sourceforge.net/nrrd/format.html

Or if you mean in memory the vtkTensor is described here: https://vtk.org/doc/release/6.1/html/classvtkTensor.html
