I want to use [nifti\_1\_header](https://vtk.org/doc/nightly/html/structnifti __1__ header.html) struct in **vtkNIFTIImagePrivate.h**. I find the header file does not exsit in my vtk install path. I guess that I have missed some option in cmake. So, I want to know how to make correct setting to deploy the header to the install path. Or, I have to copy the header to the path manually? Thanks in advance.
B.T.W. I have chosen the **vtk\_group\_imaging** option in cmake.

As the name suggests, that API is private to VTK and not an exposed API. Though it is just some C declarations. @dgobbi Is there another source for these data structures that could be used?

The `nifti_1_header` struct is defined in the [nifti1.h](https://nifti.nimh.nih.gov/pub/dist/src/niftilib/nifti1.h) header from libnifti.
For manipulation/copying of the header info, the vtkNIFTIImageHeader class is what should be used. The nifti\_1\_header Set/Get methods of this class are only intended to be used by people who are already using libnifti in their apps.
