If 'annotation_sheet.csv' is without samples, throws 'NoneType' error #444

I decided to remove the samples in the annotation_sheet.csv to see what would happen. Error was thrown - TypeError: 'NoneType' object is not iterable. It would be nice to have it respond with No samples found in your file or something.
