Thank you,
Is there a way to do such thing on the background i.e. without stopping Slicer?
I’ve seen similar topic and does @pieper 's solution with SlicerProcesses extension is able to help me? I’m going to execute heavy computation that may take long time and it would be pretty attractive to run it on the background and to see all output somwhere in Slicer GUI.
Haven’t tested SlicerParallelProcessing yet.
And the latest option probably is python cli module, but it scares me a little as it claims to write GUI in XML
