CLI example not working

[rsavjanimdphd]

Hi all,

The example on the main page for the CLI use case is not working. Even downloading the example images, the warped image does not actually warp the image at all.

`wget https://www.hgreer.com/assets/slicer_mirror/RegLib_C01_1.nrrd
wget https://www.hgreer.com/assets/slicer_mirror/RegLib_C01_2.nrrd

unigradicon-register --fixed=RegLib_C01_2.nrrd --fixed_modality=mri --moving=RegLib_C01_1.nrrd --moving_modality=mri --transform_out=trans.hdf5 --warped_moving_out=warped_C01_1.nrrd`

This does not generate any reasonable work on the output warped_C01_1.nrrd file.

Using the jupyter notebook example does work, however.

Thanks.
