Dear all Is there a way to avoid console calls in OrientScalarVolume such as OrientImage --orientation Axial ${MRML_DATA}/fixed.nrrd ${TEMP}/OrientImageTestAxial.nrrd as defined in the documentation ? I want to use some kind of logic from it to generate a temporary node to be exported …

Ok I found the solution The OrientScalarVolume is a cli module, so the way is def reorientNode(node, orientation): parameters = {'inputVolume1':node, 'outputVolume':node, 'orientation':orientation} slicer.cli.run(slicer.modules.orientscalarvolume, None, parameters, True) This was pure luc…

[image] Alex_Vergara: This was pure luck as none of these parameters are documented Documentation is the XML file. You can also find a convenience script here that lists all parameter names.

[image] lassoan: Documentation is the XML file. This XML file ? So I assume for all cli modules is the same, right? OK that is a better way than try and test :wink: Thanks for the hint!

Yes, that’s the XML file. Command-line arguments and GUI is documented in the Slicer wiki , too, but the parameter names are only described in the XML file (or you can list them using the script linked above).
