Hi, everyone!  
I’m writing a scripted module and I want to replicate the behavior of “_remove all markups from the active list_” from the module “_markups_” to my module. I have already replicated the behaviors like adding fiducials and get the coordinates of the fiducials but I just cannot replicate the one to delete fiducials.  
Does anyone know how to proceed?

Thank you!  
Andrea

GetActiveListID() in the markups logic has the current id, then just RemoveAllMarkups()

```
markupsNode = slicer.util.getNode( slicer.modules.markups.logic().GetActiveListID() )
markupsNode.RemoveAllMarkups()

```

Or just remove a single markup with:

`markupsNode.RemoveMarkup(0)`

which will remove the Nth Markup
