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. Here is some more information about my data: 15 3D landmarks on human faces (object symmetry) 479 individuals 15 landmarks from 5 individuals digitized a second time Sex and age as additional main effects I realize I need to include a classifier that indicates a repeat (to be added as an Error classifier), but I am unsure how to import these data. So far, I have imported 1) the original data text file which includes the identifier and the XYZ coordinates for the original 15 landmarks and 2) a classifier text file which includes sex and age as covariates. I have separate XYZ coordinates for the repeat landmarks, but I don't know how these should be imported to implement the "repeat" classifier. Any assistance you could provide would be greatly appreciated!
