Hello friends, I'm using a mixed landmark/semilandmark approach to assess morphological differences of canid scapulae, and I'd like to know if there is any kind of method to estimate the ideal number of semilandmarks to use, based primarily on the outline to be analyzed (and maybe on the number of landmarks - I think many semilandmarks will make the landmarks "less important", right?) A co-worker has told me of a method for evaluating the number of points for extended eigenshape analyses, and we were planning on trying that same estimation method in this case. Is there a problem with this approach? Are there better ways to do this? Thanks a lot for the help!
