I have now made a new .ndx file as written in the wiki - and it works!!! :-) Thank you very much for your time Justin, I think what had confused my was the way the .ndx file was made in 3.3.3 and then the previous threads about the "new way" to make .ndx file in gromacs 4.0.x Anyway, I'm very happy now! Thanks again.

The information about how to create index groups seems to fit better there.
