Hi everyone,

I am working on the scripted module development, trying to edit the `vtkMRMLSequenceNode`.  
However, did not find any functions like `RemoveNthDataNode()`.

How could I remove the NthDataNode?

Thank you very much in advance!

You can use this method:

```
sequenceNode->RemoveDataNodeAtValue(sequenceNode->GetNthIndexValue(n));

```
