Dear All,
I was running dt_recon on my DTI data and one output file is the eigvals.nii -- maps of the eigenvalues. I know that the diffusivity along the principal axis, λ1 represents the longitudinal diffusivity or the axial diffusivity (or even the parallel diffusivity λ∥).Can you please advise me how I can get my first eigenvalueλ1 from my maps of the eigenvalues?
Thank you for your time and help. AK
