I want to implement the experiments, while i do not know how to download the file used in the example.  
for instance  
“parser.add\_argument(‘filename’, help=‘Input volume e.g. Frog/frogtissue.mhd.’)”  
where is the frogtissue.mhd?

Hello @888yyh,

You can find `Frog/frogtissue.mhd` here : [https://gitlab.kitware.com/vtk/vtk-examples/-/tree/master/src/Testing/Data/Frog?ref\_type=heads](https://gitlab.kitware.com/vtk/vtk-examples/-/tree/master/src/Testing/Data/Frog?ref_type=heads)

But if you want to try some examples from **vtk-example** , I recommand you to clone the repository in order to have all data directly: [https://gitlab.kitware.com/vtk/vtk-examples/-/tree/master?ref\_type=heads](https://gitlab.kitware.com/vtk/vtk-examples/-/tree/master?ref_type=heads)
