EXAMPLE

       Register image test.v to image ref.v by using a spline transformation with  a  coefficient
       rate of 5  and write the registered image to reg.v. Use two multiresolution levels, ssd as
       image cost function and divcurl weighted by 10.0 as transformation smoothness penalty.

       mia-3dnonrigidreg -i test.v -r ref.v  -o  reg.v  -l  2  -f  spline:rate=3   image:cost=ssd
              divcurl:weight=10
