Hi Shiras,
Another user had the same error some years ago :
http://public.kitware.com/pipermail/rtk-users/2012-November/000028.html
It seemed to be a GPU memory size issue.
Can you tell what GPU you use, are what are the size and number of your
projections ? Can you try with a single projection (you can use the
"rtksubselect" application to create such a dataset out of yours) ?
Best regards,
Cyril

Dear Cyril,
Thanks a lot. Now rtkramp.exe works with cuda option.
I am trying to integrate rtk cuda ramp filter into my recon program. I
read the projections with ProjectionsReader and pass image pointer to
cuda ramp filter pipeline using
cudaRampFilter->SetInput(projections);
I am getting runtime error and it says
Error during cuda ramp filtering ::
D:/programming/cpp/ext_libs/rtk_1_2/src/code/rtkCudaFFTConvolutionImageFilter.cu
:97:
itk::ERROR: CUFFT ERROR #2
Do I need to enable or disable any parameter while reading projections
to get rid of this error? I changed rtk_proj_reader_->Update
to rtk_proj_reader_->UpdateOutputInformation();
But I am still getting the error.
The error exists only with CudaFFTRampImageFilter
and FFTRampImageFilter works fine.
With regards,
Shiras

Hi Shiras,
We found that bug recently with Sebastien Brousmiche and fixed it,
at least for the use case we were considering. Can you try with
the git master version of RTK ?
Alternatively, you can replace
reader->Update()
with
reader->UpdateOutputInformation()
in line 61 of rtkramp.cxx and see if it fixes the problem.
Regards,
Cyril
