[vtkusers] vtkNIFTIImageReader.h: No such file or directory

[Francisco Lopez de la Franca]

Hi.
Thanks a lot. I've just downloaded VTK 6.2.0 and I've realised that there
it is what I need.
But, I take advantage of this moment to tell about another problem.

I read a NIFTI file (abc.nii) through vtkNIFTIImageReader. Its output is
passed to either vtkHull or vtkDelaunay3D in order to get the convex hull
of the objects in the Nifti image.

And, in the end, I write their result with vtkNIFTIImageWriter.

The compilation goes right, but the execution (on a Windows system) does
not produce anything and I hardly see a "command prompt" window flashing
only once, but I am unable to read its content.

I think there must be some incompatibility between the output of
vtkNifitiImageReader and the input to vtkHull or vtkDelaunay3D, or
something similar.

Any suggestion on how to read a NIFTI file and get its convex hull and then
write it to another Nifti file.

Thank you very much.
/Francisco
