my notes..

• this code works locally:

"import sys; from Slicer import slicer; volNode=slicer.VolumesGUI.GetLogic().AddArchetypeVolume('/home/haehn/data/Image00_LCA.nrrd','Liver',0); matrix = slicer.vtkMatrix4x4(); volNode.GetIJKToRASMatrix(matrix);

outputNode=slicer.MRMLScene.CreateNodeByClass('vtkMRMLScalarVolumeNode'); volumeNode=slicer.MRMLScene.AddNode(outputNode); volumeNode.SetAndObserveImageData(volNode.GetImageData()); volumeNode.SetIJKToRASMatrix(matrix); volumeNode.SetModifiedSinceRead(1); slicer.VolumesGUI.GetLogic().SaveArchetypeVolume('/home/haehn/data/test.nrrd',volumeNode);"
