[Rtk-users] rtk has no attribute "Reg1DextractShroudSignalImageFilter"

Hi,
This filter is indeed not wrapped currently due to the notwrap extension:
https://github.com/SimonRit/RTK/blob/master/wrapping/rtkReg1DExtractShroudSignalImageFilter.notwrap
I have opened an issue to track this down in the future:
