Hi,
I would like to ave some more information about the flag "use fractional
anisotropy to constrain track". in the FSL website I found only:
"Use this option if you want the fractional anisotropic volumes (stored in
merged_f<i>samples) to influence the tractography.
The tracts stop if the anisotropy is lower than a random variable between 0
(low anisotropy) and 1 (high anisotropy)."
But what is the value of this random variable and is there a way to set or
change it?
In what cases is it suggested to use this option?
Thanks,
Marica.
