Hi Ryosuke,

The problem comes from the deformation field which is in 3D where your 
images are in 2D.

If you want to open it anyway you can just modify the mhd file which is 
just a text file describing the data. I attached my modified deform3.mhd.

vv fixed3.png --overlay moving3.png --vf deform3.mhd

After modification vv can open it on my computer.

Kind regards,
