I have generated VTK file using slicer 4.13 version.

The VTK file looks like below.  
 ![](https://discourse.vtk.org/uploads/default/original/2X/7/78e44f43d8fc311cfb74292526f3b29af375072c.png)

If i try to display above file in 3D view means. It wont align using both LPS and RAS option.  
It will be like below in slicer view.

If i change the vtk file like below. (Removed - SPACE=LPS) (second line of vtk file).

Any suggestion how can i fix this problem?
