Dear Morphomet Community I have read an article of the Dr. Kingenberg of the journal Symmetry 2015 of Fluctuating Asymmetry with a very complete overview of the methodology
I understand that the Software MorphoJ is very easy to use and I have been trying to work in Fluctuating Asymmetry with it in GM. I wanted to ask the other researcher in the community if anyone have some idea and can help. I am confused with the procedure in MorphoJ of the calculation of the *intensity of Fluctuating Asymmetry * I read some articles that they use a regression of Shape with FA Scores, using the dataset provided of the Procrustes ANOVA... and there are two type FA Scores: Procrustes FA Scores and Mahalanobis FA Scores... My question: Can I use this in a regression with the symmetric component or shape (shape vs Procrustes FA Scores) to represent the intensity of FA? Is this data really showing intensity? Is that real Fluctuating Asymmetry? Please I need a simple answer to see if I'm misunderstanding it When I saw a Regression of Shape vs Procrustes FA Scores and points are located in higher values of Shape FA Scores, Its ok said that this individuals have higher Fluctuating Asymmetry? I have a feeling that this "Procrustes FA Scores" is Procustes distance between left and right side of the structure or I'm wrong... Your expert comments will be very valuable for me and also for another student that is working with MorphoJ in this topic. If not there is another way to calculate the intensity of Fluctuating Asymmetry in Geometric Morphometrics? I wanted to evaluate for example population exposed to pesticide and not exposed and see the intensity reflect or not developmental instability or is only an artefact of the methodology and we have to act with caution.
