Can you provide an example of the whole process?

In pdp_bench.c, the public key is only used in pdp_proof_gen, which seems wrong. I think that in chanllge stage(pdp_challenge_gen), the verifier should use the public key, and the verifier should not need the data file.But in pdp_challenge_gen, you have to data file to go on.Can you provide an example of the whole process?
