[Insight-developers] Query regarding repeated use of output buffer

[Gaëtan Lehmann]

Hi Richard,

What are the errors ?
Reading and writing to/from the output image should not be a problem.  
If you update the repository (I think you are speaking of the  
vanHerkGilWerman one), I can also give a look at the result and at  
the code.
