Greetings,

I am using python2.5.1 and modeller version 9v3 on a Mac desktop (OSX 10.4.8).

I saw a similar post in the discussion board regarding the compare.py script of the tutorial where the function call generated an error message. However, the information therein didn't really help me.

I also referred to the user manual and found that in my version of modeller, malign_3d has been deprecated and that I should use salign. However, salign (in the context of the tutorial exercise) does not return an object that can be used to continue the tutorial.

I am running the compare.py script from a directory on my Desktop separate from the modeller installation directory (should I be running the script from within the modeller directory?)

For posterity, I have included my 'version' of the compare.py script and the error message from the python interpreter.

Thanks for your time and consideration in this matter.
