Hello everybody. I made at last my first attempt today : I have defined 
my script "script.py" (attached), put it in the same folder as my 
executable "yade-trunk" where is already located the .xml that the 
script will use.
Finally I typed ./yade-trunk script.py but there was no difference 
compared to typing only ".yade-trunk"... In the first case also the GUI 
appears and nothing else happens... Here are the outputs of the console :

jerome@c1solimara-l:~/YADE/bin$ ./yade-trunk script.py

Constructing SerializableSingleton  (if multiple times - check 
'-rdynamic' flag!).

Does someone see why I can't launch my python script ? Thanks

Jerome

o=Omega()

# loop over different loading modes
for mode in ['DNC','DTC']:
    # load the original state
    o.load('Test.xml')
    # get the engine you want to modify
    je=o.labeledEngine('DirecResearchEngine')
    # change engine parameters depending on the loading mode
    if mode=='DNC':
       je['theta']=0
       je['nbre_iter']=1000
    elif mode=='DTC':
       je['theta']=90
       je['nbre_iter']=1000
    # run 1000 iterations and wait (True) until they are done
    # you could use different criterion of when to stop, but this one is the simplest since it is known beforehand
    o.run(1000,True);
