I started to run some experiments with tree-to-string models and I would like 
to look closer at the derivations of the best hypothesis. Could someone explain 
me how to understand the trace-information and also how to get output that 
looks more like the ones shown at 
http://www.statmt.org/moses/?n=Moses.SyntaxTutorial#ntoc5

I have input like this:

<tree label="ROOT"> <tree label="NOUN"> Resumption </tree> <tree 
label="adpmod"> <tree label="ADP"> of </tree> <tree label="adpobj"> <tree 
label="det"> <tree label="DET"> the </tree> </tree> <tree label="NOUN"> session 
</tree> </tree> </tree> </tree>

and rule-tables that contain rules like the following:
Resumption [NOUN] ||| reprise [X] ||| 0.103716 0.25 0.656868 1 ||| 0-0 ||| 19 3 
3 |||
Resumption [adpmod][X] [ROOT] ||| reprise [adpmod][X] [X] ||| 0.110561 0.25 
0.110561 1 ||| 0-0 1-1 ||| 0.999999 0.999999 0.999999 |||
Resumption of [adpobj][X] [ROOT] ||| reprise de [adpobj][X] [X] ||| 0.110561 
0.0699863 0.110561 0.391762 ||| 0-0 1-1 2-2 ||| 0.999999 0.999999 0.999999 |||
Resumption of the session [ROOT] ||| reprise de la session [X] ||| 0.110561 
0.00885433 0.110561 0.101433 ||| 0-0 1-1 2-2 3-3 ||| 0.999999 0.999999 0.999999 
|||


My trace is then as follows:

I expected to see rule applications that include NTs like ROOT, NOUN, adpmod 
etc. but I don't see any. Do I have to add other flags to get this kind of 
information?

Thanks in advance!
Best,
Jörg
