The first set of code I got from the Nhigh.pyw file which you run to use nhigh. The second set I got from the nhighlib.py file.
Now I am almost complete illiterate when it comes to python, so any help would be great. Again I am wondering if I could edit one of these files, or if someone could tell me another quick way like running something in python shell, so that I could get the demo data for these runs quickly.
Also you can download Nhigh here.
