[Rtk-users] error in generating projections for Shepp-Logan phantom

[Howard]

Hi,

I was trying to run the Shepp Logan phantom example and got an error
when creating projections of the phantom file by running the command:

 rtkprojectgeometricphantom -g geometry.xml -o projections.mha
--spacing 2 --dimension 256 --phantomfile SheppLogan.txt

The error is shown like this:

ExceptionObject caught with ppc->Update() in file
/sc/orga/work/howard/usr/local/ITK5/ITK/Modules/Remote/RTK/applications/rtkprojectgeometricphantom/rtkprojectgeometricphantom.cxx
line 111

itk::ExceptionObject (0x1f72be0)
Location: "unknown"
File: /sc/orga/work/howard/usr/local/ITK5/ITK/Modules/Remote/RTK/src/rtkGeometricPhantomFileReader.cxx
Line: 42
Description: itk::ERROR: Error opening File

As you can see, I am using ITK5 which include RTK as a module. How can
I quickly fix the problem? Thanks!

Howard
