  1. Each class consists of microscopy images of the terminal bulb of C. elegans nematodes taken at ages 0, 2, 4, 6, 8, 10, 12 days. As the table shows, the similarity values are higher for neighboring age groups. The dataset can be downloaded at http://ome.grc.nia.nih.gov/iicbu2008/terminalbulb.tar.gz.
