I did according to [Create DICOM series using python](https://discourse.slicer.org/t/create-dicom-series-using-python/22871)

But it is throwing in getNode raise MRMLNodeNotFoundException(“could not find nodes in the scene by name or id ‘%s’” % (pattern if (isinstance(pattern, str)) else “”))  
slicer.util.MRMLNodeNotFoundException: could not find nodes in the scene by name or id.

I want python script so I can convert ni.gz files into DICOM series.
