Hi Hieu, Sorry about the delay in writing back -- I've had a busy last few days.
Yes, I think it would be great to have the -print-alignment-info flag re-implemented. We could in theory get the alignment information from a separate output file, but it would be much more convenient to have it as an extra field next to the one-best translation, as before. Would you be able to let me know when the flag is re-instated so I could check out the right version of the code? Thanks a lot! Greg.
