			function measureRimInclination(obj)
			% Glenoid rim inclination is the angle between the glenoid infero-superior line
			% and the line that goes through Trigonum Spinae and Spino-Glenoid notch.
			%
			% obj.measureInferoSuperiorLine() must have been run before measuring the
			% glenoid retroversion.
			TStoSG = Vector(obj.scapula.trigonumSpinae, obj.scapula.spinoGlenoidNotch);

			rimInclinationRotation = vrrotvec(obj.inferoSuperiorLine.vector, TStoSG.vector);

			% Unlike glenoid retroversion angle, glenoid rim inclination method doesn't set
			% the sign of this angle which should be compared to the rotation axis alignment
			% with scapular PA axis. However, this alignement depends on the shoulder side.
			% It's assumed that glenoid infero-superior line will always be aligned with
			% scapular IS axis, and TStoSG line will always be aligned with scapular ML
			% axis. Therefore glenoid rim inclination angle will always be a positive number.
			obj.rimInclination = rad2deg(rimInclinationRotation(4));
