Hi Saad.
sorry, I try to explain better.
I start from a number of patients DTI study (file .nii.gz), use the
technique TBSS then I use the tbss_non_FA to retrieve the eigenvalues and
working separately with the eigenvectors. Now I have L1, L2, L3, V1, V2, V3
and I would like rebuild final DTI.
I want a single image ( for example, template.nii.gz ), where, each voxel
contains a matrix 3x3 (tensor).
Thanks
Eddy
