Extract FA value profile along the fibers

Hi MRtrix3 experts,

I’m writing to ask if there is any way to extract the FA value along the fibers? Fiber tracking results are all saved in very high spatial resolution grids, which is usually not the DTI/FA volume’s resolution. Instead of me interpolating FA into finer grids that approximately match fiber tracking domain, is there any way that I can use MRtrix to do that?

Thanks!This thread seems to be exactly what I want. I’ll give a try.
