Hi Kazu
You may have passed the wrong FLIRT transformation to probtrackx.
Please make sure that:
1. The transformation from b0 to struct is correct (overlay the result on the structural in fslview)
2. You pass to probtrackx the _inverse_ of the above transform (i.e. from struct to b0)
3. Your seed/target masks are all in structural space
Cheers,
Saad.
