Electron localization function

[rose]

Hi everyone,
I try to use Electron localization function in ATK 11.8.2 but i got error even using the example of
http://quantumwise.com/documents/manuals/latest/ReferenceManual/index.html/ref.electronlocalizationfunction.html

I got following error:
elf = ElectronLocalizationFunction(molecule_configuration)
NameError: name 'ElectronLocalizationFunction' is not defined

how can i solve it?

thanks
