Hi
Experts,
I
posted earlier, but I believe my message has not been posted
due to the size of attachments so I’ve removed them.
I
am using bbregister to align functional data to anatomical
space. I have been using the bbregister command with a
combination of different flags. However, there appears to be
varying levels of poor registration.
The
first command I used included flags for a whole brain ref
image and the --init-header flag. This leads to a
misalignment.
bbregister
--s PPT_1x --feat
/Data/PMA_retinoScans/PPT_1x/run1_pre_processed_functional.feat/
--int Data/PMA_retinoScans/PPT_1x/WholeEPI.nii.gz
--init-header
I
then removed the –int (whole brain reg image) flag. Again
the registration is massively misaligned.
bbregister
--s PPT_1x --feat
/Data/PMA_retinoScans/PPT_1x/run1_pre_processed_functional.feat
--init-header
I
then removed the –init-header flag. Again poor registration.
Then
I removed both flags. This was the best registration, but
even this still looks a little bit off to me. You can see
that around the occipital lobe (reg3 attached), there white
matter isn't aligned very well.
bbregister
--s PPT_1x --feat
/Data/PPT_1x/run1_pre_processed_functional.feat/
Can
anyone give me any advice on this? I really am unsure as to
which why these flags failed to aid registration. I have 3
other participants from a different dataset for which the
bbregister pointing to the feat directory and the
–init-header flag worked perfectly. Have I missed an
important step that could explain why no combination seems
to register the data correctly?
Any
advice would be great.
Thanks
in advance,
Mason
