Hi Marta,

I admit that it is confusing.
The two files needed for the fiber tracking (*.ani and *.vec) is labeled as
FA and eigenvector0 in DtiStudio.
If you are using DtiStudio to process your data, it saves various images
after the tensor calculation, which should include these FA and
eigenvector0 files.
