The notebook loads a metadata CSV into a pandas DataFrame and verifies that all referenced image files exist. It then groups the data by subject and slice direction, counting the number of slices for each binary label (0 or 1) with `groupby` and `apply`, before restructuring the result with `unstack`. The output is a cross-tabulated summary showing slice counts per subject, direction, and label.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-59ae1a59826b5b7e09a35c922852cb2b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
