Hello, thank you very much for this article on structure decoding automation, I'm a beginner and I want to learn your program with my own data. But I don't understand the composition of the file and the input data, when I run the code a random file name appears. I can't understand what this file name is? FileNotFoundError: [Errno 2] No such file or directory: '. /Dataset/Australia/Rotations/Australia_140.mat' or do you have a relevant video here to teach me how to train?

Thank you again!

I seem to get that it means dividing the training set into 9 pieces like in the diagram in the article right?
