Faranak, I just dug into this a little deeper and you just need to add one line of code to the Python Extractor. Make the FIRST line:
#!/usr/bin/python Then retry running the Extractor as ./CARVE_KML_Extractor etc.... With that line first, the shell will realize the script is a python program and run it properly. It will send a lot of messages to the Terminal, but it will run. I designed the script to be run using python. Hope that helps, and sorry to hear about your eyes. -Cameron On Sat, Apr 16, 2011 at 1:25 PM, Cameron Goodale <[email protected]> wrote: > Faranak, > > I haven't tried the code yet, but I think the problem is you call python > code like this: > > python CARVE_KML_Extractor.py > > I think using ./ tells the she'll to run it.
