The reordering model is learned on training step 7. The training script needs you to specify which reordering will you use during decoding because it has to generate a specific file for it. It is called something like extract.o in your model directory, and finally reordering-table.
Otherwise the reordering-table file will not be correct. If you train it to use only the distortion model (one weight) you will not be able to change to any lexicalized model because you'd need an additional table. So, train again from step 7 (--first-step 7) with the new reordering (--reordering msd-bidirectional-e) and check that extract.o and reordering-table are generated accordingly. I hope it helps.

Does anyone else know what might be wrong with changing the reordering model? has anyone done it successfully? I really cant get it working and there's no help on the web.
