Hi,
It is really unusual to see a problem of this magnitude in a single-subject registration. Are you sure that the voxel sizes are correct in the image? That's one problem that could cause such a result. Otherwise, let us know what settings you are running, and if you are using a fieldmap, try turning the fieldmap correction off and see if that makes it better. This isn't the solution to the problem, but it will help us track down what the source of the problem is.
All the best,
Mark

It looks like the problem is occurring at the first stage of the registration (i.e examplefunc2highres) as demonstrated in the attachment. The subsequent highres2standard registration looks fine.
