Installing new components with SimpleITK Elastix #457

[zwep]

Hi, Ive done the SuperBuild for SimpleITK - Elastix and want to play around with different parameters. For example, I want to use the FullSampler as ImageSampler. However, when running I get the following error in the error log

Error: FullSampler(index 1) - This component is not installed! ERROR: error occurred while creating ImageSampler 0.

itk::ExceptionObject (0x85addb0) Location: "unknown" File: /home/bugger/bin/build_simpleelastix/Elastix/Core/Kernel/elxElastixMain.cxx Line: 827 Description: itk::ERROR: ElastixMain(0x8338ad0): The following component could not be created: FullSampler

ERROR: One or more components could not be created.

How can I install this (and other) components?

EDIT: Just installed and used Elastix without SimpleITK inbetween. Even there I get the same error message. Not unusual behaviour of course. But even more curious now how to install additional components

SimpleElastix by default doesn't use the FullSampler component. You can manually enable the desired sampler by changing the CMake flag in SimpleElastix/SuperBuild/External_Elastix.cmake by changing the line -DUSE_FullSampler:BOOL=OFF to -DUSE_FullSampler:BOOL=ON. I'd expect the same result for Elastix compilation.
