Hi -
actually unfortunately it is not - this is partially my fault - sorry.
Fslview displays the vectors x-flipped and should not, so if you want
to use neurologically ordered data with tractpgraphy, the vectors have
to look *x-flipped* in fslview.
Again, sorry - this will be fixed in the next release.
