Methodology of directional asymmetry adjustment in facial asymmetry measurements of long-tailed macaques.

Facial asymmetries consist of fluctuating asymmetry, directional asymmetry, and antisymmetry. Measurements in facial asymmetry studies may be inaccurate in the presence of directional asymmetry (DA) as DA have genetic basis. This paper explores the methodology of DA adjustment in facial asymmetry me...

DA was found to be present in one template of manual measurements. After adjustment for DA, high correlation of asymmetry results between manual measurements was found.
