[Mrtrix-discussion] Question on fiber tracking

[Donald Tournier]

Hi Michael,

Modifying the overlay plots would be possible, but probably more work than
I've got time for... On the other hand, you might find that simply scaling
the glyphs would be sufficient for you to see the secondary fibre
orientations. You can do this by scrolling the mouse wheel in the
orientation plot sub-window, and then updating the main display (e.g. by
windowing the image slightly). I agree there's probably more intuitive ways
of implementing this, but that's the way to do it at the moment...

Cheers,

Donald.
