[Error] failure applying RBV

[rullator]

Hello,

I try to run the Toolbox using the RBV approach on our data and got the following error. In my opinion, the origins are the same. How can I modify the given tolerance?

Hi @rullator,

I think you would probably want to put something like: multiplyFilter->SetCoordinateTolerance(1e-2) in lib/petpvcRBVPVCImageFilter.txx at line 98. However, there may be more filters affected than just the MultiplyImageFilter, in which case perhaps try setting:

itk::ImageToImageFilter::SetGlobalDefaultCoordinateTolerance( 1e-2 )
itk::ImageToImageFilter::SetGlobalDefaultDirectionTolerance( 1e-2 )

at the top of RBV.cxx.

Kind regards,

Ben

Thank you - worked for me!

PS: Just to be sure: If I want to apply RBV, my mask is a 4D file, containing each ROI as a separate binary volume, right?

Hi,

For RBV, yes the mask needs to be 4D with each ROI as a separate volume. The volumes don't have to be binary. The voxels values can be 0 <= x <= 1.

Kind regards,

Ben
