You want us to keep guessing? And without supplying any new information? There's no such thing as a yml image in Python, though there might be some library that supports such a thing with some class structure. And you just might have downloaded it from the http://www.ymlgroup.com/obscurehiddenlocation/downloads site, and imported it using from notzanzibar import DataType. Then you'd have instantiated it in some code like data = DataType(filename) and then the type of data would be notzanzibar.DataType and the docs would be probably available somewhere on www.invalid.com/docs The only new guess: A 3D image would presumably have 3 subscripts, and you're only supplying two. If you want help, be explicit: 1) what version of CPython are you using, and on what OS? 2) what web site did you download some extra library from ? 3) what import statement did you use ? 4) How are all those global variables initialized ? 5) What command did you use to start the script ? Did you run it from command.com, or from some IDE ? 5) Exactly what error message did you get, including the traceback ? 6) What have you done to try to figure out your own error? -- DaveA -- http://mail.python.org/mailman/listinfo/python-list
