Hi,
You need to register your image and either load the image
that is transformed, where the coordinates will be consistent
with Talairach coordinates (or more strictly, MNI coordinates),
or you can use the original image and apply the transformation
to the coordinates using img2stdcoord. It depends what is
important.
I recommend looking at the FSL course section on registration.
Be warned that MATLAB voxel coordinates and FSLView
voxel coordinates will be different, and you need to use the
FSLView ones (which start at 0, not 1).
All the best,
Mark
