How to concvert an etf file to a lily-pdf (newbiequestion)

[Samuel Van Ransbeeck]

Hello
I had some problems with Open Music 
and a responsible from the ircam helped me by concerting the 
results from a patchwindow to a pdf usibg lilypond. 
I want to do that myself now, but i am really 
new to lilypond and with the instructions in the 
documentation i don't get results, 
probably (most probably) i use wrong syntax.
can anyone type me correctly just what i have to type?
Thanks
Samuel
