As someone suggested me, i read the documentation about the Migration to Slicer 5.0  
I have this method called `SetNthMarkupDescription()` but i found no clue into the guide except for this line:  
**vtkMRMLMarkupsNode::GetNthMarkupSelected() is replaced by GetNthControlPointSelected()**

It’s not SetNth and i’ve check if ControlPoint existed in the Slicer 4, but no. There is no method with ControlPoint in it.

I made a guess and i noticed that exist in Slicer 5.0 a method called SetNthControlPointDescription.

So i changed `SetNthMarkuptDescription` into `SetNthControlPointDescription`. Can someone confirm that i did right?

Yes, all `Get/SetNthMarkup...` methods have been renamed to `Get/SetNthControlPoint...`.
