Dear Antonella,
In theory, FA can be sqrt(3/2) = 1.2247449. This occurs if eigenvalues 2 and 3 are zero. You will find these high FA values (>1) mainly outside the brain.

Dear all,
I use dt_recon to process my DTI data and get my fa.nii for the individual subjects. I wonder if the FA values can be greater that one since for all my subjects I got the FA max? value graeter than one. Is something wrong with my data or this is acceptable? I saw in? most of the papers FA<1 so 0<FA<1.
Thank you. Antonella
