Hi Kate, If I understood correctly, I am not sure that you can do a Procrustes ANOVA-based FA test on a list of individuals where only few of them have been digitized a second time. If this is the case, then I would suggest this approach (might be other ones using what you already have but this is fast and works for me):
- have a separate landmark file that contains only the specimens you repeated (5 landmarks sets + 5 repeatded landmark sets = 10 landmark sets), whose names end on "-rep1" and "-rep2" or something alike but with the same amount of characters. - create a classifier (eg "repeat) using the last characters of the name (in my example, first character would be -5 and the last, -1). Remember you have to create an "individual" classifier that covers all the remainig characters. - run the procrustes ANOVA on this 10-individuals landmark set using as error term the "repeat" classifier. This way you will be able to quantify variation due to repeated landmarking against variation due to individual*side. I hope this helps, Viviana 2017-01-30 20:56 GMT+01:00 Kate Rusk <kmru...@gmail.com>: > Hello everyone, > > I am a bit confused about how to properly import and classify data for a > Procrustes ANOVA in MorphoJ.
