Please help me about how to generate word alignment information in Nbest results with moses

Dear,

       I am a student researching on SMT. Moses is an open powerful tool. Recently I want to generate word alignment in N-best output with Moses.

      For example, the below sentence is outputted by moses and it has word alignment information  such as "0=0".

      A  sentence generated by moses   :        however , because the two sides still exist . ||| 0=0 1=1 5=2 4=3 2=4 3=5 6=6 7=7 8=8

     The result above is  produced by Phrased-based model in Moses. And  I tried on Syntax-based model in Moses  but  I  failed. 

     Can Moses generate  word alignment information  with Syntax-based model ? And how to do it ?

   

     Thank you in advance

i don't think it's available for syntax-model.

in moses-cmd/src/IOWrapper.cpp line 454, there is variable
   includeAlignment
however, in moses-chart-cmd/src/IOWrapper.cpp, this is commented out.

you're welcome to change the code to enable it. Email me if you have any problems
