I want to manipulate the module created from the segmentation.  
what i did was to export the segmentation to modules  
and now I want to manipulate the colors and the visibility of the modules.  
here’s the code:

```python
#export segmentation
segmentationNode=getNode(‘Segmentation’)
modelHierarchyNode = slicer.mrmlScene.AddNewNodeByClass('vtkMRMLModelHierarchyNode')
slicer.modules.segmentations.logic().ExportVisibleSegmentsToModelHierarchy(segmentationNode, modelHierarchyNode)

```

I found out the following way to manipulate the model:

```python
vtkLWM=getNode('Left-Cerebral-White-Matter')
vtkLWM.SetDisplayVisibility(False)

```
