Extracting diffusion tensor from DTI images

Hi everyone,

I’m having a lot of trouble with the software so far. I am trying to a) visualize the tensor field of dti images and b) extract the 3x3 tensor matrix from each voxel of the images (or directly the eigenvalues of the matrix). In the tutorials online, it seems that they focus on converting the DWI image to DTI, then working from there. I keep getting errors (b0 not detected) in the conversion and i do not have DWI images for all my patients. I would like to extract the information I need directly from loading the DTI images themselves onto the software. Is this possible? What is the protocol for this? Aditionally, I would need to convert the DTI images to nhdr, but would the DWI converter still work for this?

thanks!
