Fig 12. Boxplots comparing inter- and intraobserver error Researchers 6 and 8 to the variation in different species of Macaca for the Full and Semilandmark only configurations after semilandmark sliding.

(A) Full landmarkset; (B) Semilandmark set. Note the low amount of pooled intraobserver error relative to the large amount of interobserver error between the researchers and relative to the amount of variation in different species of macaques for both landmark configurations.
