Problem with data structure

[gy61]

Hi!

Thank u for sharing these codes, they have been very helpful. But I have some problems with the data strusture.

Problem 1: the data structure of non_image, image_1 and image_2 data
After data downloading from the official archive, both non_image and image data are merged in one folder, so could you maybe specify how to partition non_image, image_1 and image_2 mentioned in code02??

Problem 2: could not find /nda18_w_nc_pca.csv mentioned in in code06. Data link would be very helpful.

Thank u for your reply in advance. I really aprreciate it!
