 Each folder is further divided by {date}_{single or double}.
 The purpose of this data is to perform binary classification between **single** and **double**.
+Each JPG image is named using the date of data collection and the individual number. Each individual in Quartet_Apricot, Quartet_Apricot2, Quartet_Blue, ..., Quartet_Rose2 is completely separate. For example, Quartet_Apricot, Quartet_Apricot2, and Quartet_Blue each contain a JPG image of individual number 1, but these are completely separate individuals.
+The directory structure of Quartet_Apricot is shown below as an example.

 # Data collection
 This data was created by agricultural experts at Mizuho Agricultural High School in Tokyo, Japan, in collaboration with the Nakajo Laboratory at Tokyo University of Agriculture and Technology.
 
-We planted M.incana seeds in trays and tracked whether each individual became a single-flower or a double-flower. Images were taken between 2 and 3 weeks after planting the seeds.
