I have imported the Ct lung analyser extension with the extension mode because I can not find the module in extensions.

And when I run this module, I have found the issue

self.resampledVolume = slicer.mrmlScene.AddNewNodeByClass(“vtkMRMLScalarVolumeNode”, “Resampled Volume”)

if the this function runs, inputvolume value is initialized  
how can I fix this issue

OK, that explains it. This extension is not compatible with Slicer-4.10. Please use the latest Slicer Stable Release or Slicer Preview Release.

Sorry, you need to upgrade to a recent Slicer version. Any computer that was manufactured in the last 5 years should work (starting from about 300 dollars), but if you don’t want to buy a computer then you can rent a virtual machine from one of the cloud providers for a few dollars per hour. You can also find free services that can run Slicer on the web, such as [Binder](https://mybinder.org/v2/gh/Slicer/SlicerNotebooks/master?filepath=SlicerWeb.ipynb).

I am sorry but I did not mean the Money.  
I have already launched our own applications which is based on 4.10 version  
and I can not update the base code of them now  
this is a bit complex  
so if you have any solution how to use this module without updated code  
please let me know
