Hi Stefano,
When running relax, you should avoid putting any files in the relax
source code directories. These should be kept separate at all times -
otherwise the result could be severe problems that are very difficult
to understand. To see the output of the script when running in GUI
mode, you will have to open the relax controller window were all
messages are displayed. To do this, perform one of:
- Select the 'View->Controller' menu item.
- Click on the 'relax controller' button in the toolbar.
- Type Ctrl-Z.
The two numbers should be printed at the bottom. If you see errors,
then there is likely to be word wrapping problems - one line has been
split into two in the email text.
Regards,
Edward

Hi Edward,
thank you for the exhaustive answer.
I have saved the script as a filename.py file in the
/relax/Contents/Resources/user_functions directory and tried to run in
from within relax using the menu user functions (n-z) -> script
However, it does not appear to do anything.
Any hint?
Stefano
