Thank you for your help. 1) As you said, it is not necessary to use "Resample With Dataset" filter. Just "Probe Location" is enough. 2) I figured out why I got all zeros: because the input data I am using is in .h5part format and they are just points data., no surface, no grid, no volume. 3) The way to overcome this issue is use Delaunay3D to generate grid. Then use "Probe Location". Hope this will help someone who also has similar problems.
