Did you stick with the pial surface or change it to white?

For the record, I applied two changes:
1) I used my AAScout scan as --int and it worked.
2) As you suggested I also used --t2 rather than --t1 this time and it also
helped.
Combination of these two changes worked very well.
Thanks

A couple of suggestions ...
It looks like the new sequence is T2 weighted, so you can try using --t2
with the white surface
It may be that the fsl is not initializing the BBR registration
properly. Try using spm (which may still fail because it is partial
brain coverage). Do you have a whole-
Hi Doug,
Sorry for interrupting you again with this topic but recently we
changed couple of parameters in our MRA to increase our chance or detecting
veins. The problem is that, bbregister can not register the MRA volume to
T1 scans anymore.
As an example, here you can see the old version
Using --t2 and --bold will always give identical results. If there is
not much G/W contrast in the MRA (and there probably isn't), then you
can try using the pial surface instead (maybe more GM/CSF contrast). Use
--surf pial --t1. Use --t1 here because the GM will probably be brighter
than CSF
Hi Surfers
I want to use bbregister to register my MRA scans to the structural
scans. The first attempts by using these parameters came out OK but not
perfect:
bbregister --s --mov MRA.nii --init-fsl --reg register.dat
--bold
However, there are obvious problems around frontal areas.
