Just one more question on this - the FineRegistration works

  Hi,
  This would be a nice feature for ConcatenateImages
application, but the coregistration is not performed
here. You have to use an other application to estimate
the registration shift between images, such as
FineRegistration of even BlockMatching. However, please
note that these application were written assuming
