details about 2d datasets

[MeganHoooo]

Hi, I wanna ask how to pre-process the 2d datasets like luna16? I notice that function in the path.py file in datasets_2d folder returns different dir. What is the difference between them?
Another question is how many epochs did the author set for pretask and downstream task?
Thanks for replying.
