What is the difference between train_index and train_index_new?

I have downloaded your dataset from google drive. What is the difference between train_index.txt and train_index_new.txt, val_index.txt and val_index_new.txt?

Which one did you use in your paper? I also find the files in your code. What is the difference between them? Which one should I use?

train_index.txt and val_index.txt include the data of step 1, 2 and 3. train_index_new.txt and val_index_new.txt only contain the data of step 1.
