Hi Matt thanks for the response,

I need however do do some deformable registration on a single slice
extracted from a volume and then use this 2D displacement field (pasted
into 3D image) on the full 3D volume; in essence to just warp
one particular slice of that volume

  Deformable registration however requires 4 voxels in the third dimension
to operate which I believe from memory is because the deformable
registration uses a Gaussian filter during it's operation.  This is why I
am using just a 2D slice with zero dimensions in the third plane and then
attempting to recast this as a 3D volume dispalcement field.  Would it be
adequate to resample my initial volume to get x4 the voxels in the in slice
direction and then perform deformable registration on this now 3D chunk of
data?

Have you any other suggestions?

Thanks again
