Hello, I have a local threshold segmentation code in a scripted python module which iterates through fiducial points and runs the local threshold function. Iterating through points takes a while to do and to speed it up, I would like it to run in parallel with a scripted CLI python module. I have set a list of parameters, and I have this line of code: slicer.cli.runSync(slicer.modules.climodulecode, None, param, True, True) I am not sure what to do in terms of adding code to the scripted cli module and how to use the parameters from there. I have looked at some examples but I am still a little unclear. Thanks ---
