Good day everybody, I actually have two questions here regarding semi-landmarks:
So, I was adviced to use semi-landmarks, I placed them with MakeFan8, saved the files as images and then used TpsDig to place all landmarks, however I didn't make any distinctions between landmarks and semi-landmarks. What unsettles me is (1) that I've recently comed across the term "sliding semi-landmarks", which leads me to believe semi-landmarks should behave in a particular way. The second thing that unsettles me is whether "more semi-landmarks" means a better analysis. I can understand that most people wouldn't use 65 landmarks+semilandmarks because it's a painstaking job to digitize them, however, in my recent reads I've comed across concepts like a "Variables to specimen ratio", which one paper suggested specimens should be 5 times the number of variables. I do have a a data set of nearly 400 specimens, but it does come short if indeed I should have 65*2*5 specimens! Please, I'll appreciate some feedback :) -- MORPHMET may be accessed via its webpage at http://www.morphometrics.org --- You received this message because you are subscribed to the Google Groups "MORPHMET" group.
