Hello everyone, I am trying to compare the shape of hummingbirds' bill using photos from the dorsal view. I digitized semi-landmarks on both sides of the bill, delimited by landmarks. Then, I performed a semilandmark superimposition in tpsRelw. I understand that the next step is to symmetrize the semilandmarks since the bill is a structure with object symmetry. I've tried to do it in MorphoJ, but when I input my superimposed coordinates file, I'm not able to symmetrize without performing a GPA again. I´m concerned that the second GPA will alter the effects of the sliding process from the first GPA. Is it ok to perform a regular GPA on data that has already been superimposed using semilandmarks?
I would be very grateful if someone could give me advice on what I should do. Regards -- You received this message because you are subscribed to the Google Groups "Morphmet" group.
