This python script will analyze a .sca-file and print out the key statistics missing from the standard SCALEPACK log-file, namely [math]\displaystyle{ \lt I/sigma\gt }[/math] per resolution shell. Syntax is quite simple

./ioversigma.py <.sca-file name> <number of shells>

The number of shells is an optional parameter and defaults to 10 if omitted.
