1-1, 1-N, N-1, N-N relations

In Line 200-211 of run.py, I noticed that the code opens 1-1-id.txt, 1-n-id.txt files, etc. But I cannot find those files anywhere after downloading the ogbl-wikikg and set up everything. Did you create those files yourself? I wasn't able to locate those files anywhere after some search. Could you please share those data or point out how to find those data publicly? That'll be very useful for performance evaluation.

Thank you very much in advance!
