Dear you,
I am new to GM, I am working with a hand bone (third metacarpal) and I
have chosen 9 landmarks, I also included a ruler on the pictures a scale
and gave 2 landmarks more to mark 10mm.
I took one picture and copied this file 29 times, digitised the
landmarks with TPSdig, made one file with the 30 observations. Then I
used MorphoJ and did a procrustes fit then find outliers and the maximum
distance was 0.00011.
What I really want to do is to calculate de error after digitising 30
times the next image, to see if my landmarks are reliable, and I am not
sure how to do it, I tried to run a procrustes ANOVA, but don't
understand why I need to do this, and it asks me for classifiers and I
am not sure what classifier to include since they are all the same image.
Thank you very much for your help,
Claudia
