Hello,
There’s a few things to consider here:
- The BNA is already in MNI152 space as far as I can tell, so you shouldn’t need to register it again
- The reference for the wmfod_template to MNI step should be a T2-weighted MNI image, not a T1-weighted or label image as it is now
- Don’t use nearest neighbor interpolation while calculating the transform and warp, only when applying it to move the label image (atlas) to the wmfod_template
Generally, to figure out where the registration is failing, overlay the output image with the reference image at each stage.
Depends on what you want to do - I was giving you instructions on how to move the Atlas labels to the wmfod_template so that you could use the labels to build a connectome (using tck2connectome
) and then select the tracks assigned to the thalamus nodes (using connectome2tck
). I think this is what the authors of that paper did, but you could also approach it by warping the tracks to MNI space and then doing something similar - not sure whether one approach is better than the other.
Cheers,
Nick
