[Mrtrix-discussion] Obtaining tensor-based measures for specific fibre tract (streamline) bundles

[David Raffelt]

Hi Simon,
You can use tracks2prob (with the FA map as the template) followed by a
threshold to create mask of your bundle of interest. You can then use
mrstats with the --mask option to compute the mean FA within this mask.
Cheers,
Dave
