Hello Everyone,  
I have read somewhere in the Internet that I can implement any algorithms inside the vtkSlicerMY\_MODULE\_NAMELogic.cxx file. Is it true? If so, how do I access it from the qSlicerMY\_MODULE\_NAMEWidget.cxx file? Any help would be appreciated!

Best regards,  
Anish

Certainly, you can do that.

Please see the corresponding section in the developer’s manual:

> **[Documentation/Nightly/Developers/Modules - Slicer Wiki](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Modules#Loadable_Modules)**

I’d strongly suggest looking at examples, basically any Slicer module does this:
