Non-rigid registration of meshes

Is it ok to leave the fixed and moving image sections blank? Also, when I try to run it this way, it looks like it’s just duplicating the same mesh that was the moving mesh without doing any deformations? Finally, is there any way to get the transform out? In the following image, there’s supposed to be 3 meshes. The blue is supposed to be the fixed mesh, the yellowish/white is supposed to be the original moving mesh, and the brown is supposed to be the deformed mesh:


If it’s actually doing deformations to the moving mesh, then it should be creating a new deformed mesh right?
