Hi,

So, the script below only allows me to convert a labelmap volume that has already been added to the scene. Is there a way to modify the script so that it applies to all LabelMap volumes I load even if they have not been added to the scene?

labelmapVolumeNode = getNode(‘my\_labelmap\_name’)  
seg = slicer.mrmlScene.AddNewNodeByClass(‘vtkMRMLSegmentationNode’)  
slicer.modules.segmentations.logic().ImportLabelmapToSegmentationNode(labelmapVolumeNode, seg)
