You’d be better off by manually placing the endpoints; avoid the furthest extreme points; and results are more predictable if you avoid extracting bifurcated centerlines.

Thank you! I have solved it,and I have a new question which is that I want to save the ‘centerline curve’ and the ‘Centerline quantification’,so how to achieve that?
