In the flist, how is the image with missing parts and the true image passed?

[GedorN]

Hello! First of all, thank you for the project! I am trying to train with my own dataset and I am facing a problem. I didn't understand how the training works in the flist structure. How does the training receive the image with the missing part and the true image in order to learn the difference? I understand that this file contains the path to the images, but how does it know which is which?
