-> The contributions to the edge pixels don't add up anymore. This is somehow the 'adjoint problem' of what has been solved by Martin's fix.
Is there any chance to fix this?

ImportError: No module named plotter
As the latest master branch works on Martins machine, it is likely that this is due to subtile differences in the filesystems of OS X compared to Linux. Hence please change the naming of plotter.py in plotter or the name of the directory in order to overcome confusion and import errors.

I can implement this efficiently and without using Cython; I just need some help in the case that the array is distributed over several MPI tasks...
Implementing this would get rid of Nifty's Cython dependence.Martin ReineckeMartin Reineckehttps://gitlab.mpcdf.mpg.de/ift/nifty/-/issues/112adjoint_inverse_times vs. inverse_adjoint_times2017-05-28T06:56:12ZTheo Steiningeradjoint_inverse_times vs. inverse_adjoint_timesIf a (left&right)-inverse of an operator exists, both methods are the same.If a (left&right)-inverse of an operator exists, both methods are the same.https://gitlab.mpcdf.mpg.de/ift/nifty/-/issues/111Unitary vs. Isometric&Coisometric2017-05-28T06:56:12ZTheo SteiningerUnitary vs. Isometric&CoisometricSHT are in general not unitary but they can be (co)isometric.
