What about consensus and agglomeration steps?

Hello,

Can someone please explain about the codes corresponding to the steps consensus and agglomeration (as in the nature paper) that follows the inference.
https://github.com/google/ffn/blob/master/ffn/inference/consensus.py and https://github.com/google/ffn/blob/master/ffn/inference/resegmentation.py seems to have routines associated with these two steps. However, there is no instruction about the usage of these modules. Has anyone succeeded in running these two steps to yield the so called output ffn-c?

Thanks,
