Hi,

I have written script which takes the volume as an input and then based on the transform reorients the volume.

```
def onReorientVolumeButton(self):
    volumeNode = self.ui.inputSelector.currentNode()

    # Create a new ROI that will be fit to volumeNode
    roiNode = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLMarkupsROINode")

    cropVolumeParameters = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLCropVolumeParametersNode")
    cropVolumeParameters.SetInputVolumeNodeID(volumeNode.GetID())
    cropVolumeParameters.SetROINodeID(roiNode.GetID())
    #slicer.modules.cropvolume.logic().SnapROIToVoxelGrid(cropVolumeParameters) # optional (rotates the ROI to match the volume axis directions)
    slicer.modules.cropvolume.logic().FitROIToInputVolume(cropVolumeParameters)
    slicer.mrmlScene.RemoveNode(cropVolumeParameters)

    # Get the first volume in the scene
  # volumeNode = slicer.util.getNode("vtkMRMLScalarVolumeNode1")
    # Create a new ROI
# roiNode = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLAnnotationROINode")
    # Make new parameter node in order to use the crop volume module programmatically
    crop_module = slicer.vtkMRMLCropVolumeParametersNode()
    # Add parameter node to the scene
    slicer.mrmlScene.AddNode(crop_module)
    # Set the volume as the input volume in the crop volume module
    crop_module.SetInputVolumeNodeID(volumeNode.GetID())
    # Set output volume as the same volume to overwrite original volume (only needed if you actually want to crop the volume)
    crop_module.SetOutputVolumeNodeID(volumeNode.GetID())
    # Set the input ROI
    crop_module.SetROINodeID(roiNode.GetID())

    crop_module.SetInterpolationMode(1)
    crop_module.SetIsotropicResampling(1)
 # crop_module.SetVoxelBased(1)

    # Use the Fit ROI to Volume function of the crop volume module
    slicer.modules.cropvolume.logic().Apply(crop_module)

```

Everything works fine. Except that I have to first uncheck the visibility of the volume and then recheck it to actually reorient the volume. Is there any way that I can automatically accomplish this functionality?

Thanks
