[Insight-users] saving the registration transform to disk

[ronn kling]

So I tried what Chris suggested and got this error

errDesc = 0x000000000a708ff0 "itk::ERROR:
TransformFileWriter(000000000A704480): Can't Create IO object for file
C:\test.tfm"

My code snippet is

transform->SetParameters( finalParameters );

try {
itk::TransformFileWriter::Pointer writer = itk::TransformFileWriter::New();
writer->SetInput(transform);
writer->SetFileName("C:\\test.tfm");
writer->Update();
}
catch( itk::ExceptionObject & err ){
std::cerr << "ITK test driver caught an ITK exception:\n";
err.Print(std::cerr);
const char* errDesc = err.GetDescription();
return (-1);
}
Thanks!
