Hi everybody,

Just quick question I couldn’t find on the documentation. When using dwi2tensor it creates a 4D files with the 6 tensor coefficients. Which is the order of them? I mean D11,D22,D33,D12,D23,D13 or what?

Thanks.

NOTE: Assuming tensor matrix as:

D11 D12 D13

D22 D23

D33

Looking a bit into the data I think its D11, D22, D33, D12, D13, D23. It would be nice if someone can confirm.

That’s correct. I’ll make a note to document that in the command doc…

Thanks Still one can reverse engineering this by reconstructing tensor from eigenvalues and eigenvectors (from tensor2metric) and checking manually in which position there are (that’s how I figured it out) but it would be welcome a little note in the dwi2tensor command docs.
