Need script file for lights and darks only

Been away for a bit and now trying to work efficiently with darks and lights only (OSC). I had some help last year but can’t locate the custom script that only used those two. Can someone shoot me an SSF file that will work with just darks and lights? I’ve been thru the Calibrate docs a fair amount but don’t quite get the syntax. Would save a boatload of time if someone could just make the changes and shoot me a working script. Much appreciated.
