Hi. I would like to know if there is some way in MRtrix to compute the three eigenvalues for both DTI and DKI tensors of brain data.
Thank you,
Rosella
Hi @ros,
You’re looking for tensor2metric
! You’ll need the -value
option to specify an output filename, and the -num
option to specify which eigenvalues you require (by default it only outputs the principal / 1st eigenvalue; you’ll want to tell -num
to give you all 3 eigenvalues). Only works for the DT though; nothing available for the DKT, as far as I’m aware.
Cheers,
Thijs
ok thank you very much!
