Hello, everyone!  
I am struggling with that error:  
`itk::ERROR Image(0x55f0ab8f5690): A spacing of 0 is not allowed: Spacing is [0, 0, 0]`

The situation is the following:  
I am performing a multistage image registration.  
First stage is a `rigid transform` (`3DVersorRigidTransform`) using the `regularStepGradientDiscentOptimizer`;

After that I resample the moving image to obtained a rigidly registered image.

That image is used as the input for the` deformable stage`.  
This stage starts ok, but crashes right away with that `error message`.

I already tested the process with two different optimizers for the deformable stage: `LBFGSBOptimizer` and `LBFGSOptimizer` . No success though.

Any clues are welcome.  
Thanks,

Leo.

Sounds like you have a bug in your code. Trying to create a MWE might reveal it.

I’m not aware of how to create and handle a **MWE**.  
Could you go into the specifics of that?

I also tried to debug with Qt Creator, but no success.

My pipeline is based on `DeformableRegistration8.cxx`.  
I even tried to run the example alone, but it is running tooo slow, and the optimizer output do not sound reasonable.

Thanks.

Here are some instructions on how to create [minimum working example (MWE)](http://sscce.org/).
