Subject: Fluctuating asymmetry analysis

Hi,
I'm a new to geometric morphometrics analysis and I try to work on the
fluctuating asymmetry of vole's populations.
For this, I make landmarks and I would use MorphoJ to realise a
procrustes ANOVA. I have some voles to the North of Quebec and some to
the south I would compare the fluctuating asymmetry of each population
to characterize the stress which they are subject.
In MorphoJ, I have made the procrustes fit, and after I have created a
covariance matrice. I have also created some classifiers. One for the
geographic location I have called "geography", I discriminated north to
south population. And I created a classifier for the error of
measurements I have called "image", I put 1 or 2 respectively for the
first image and the replicate.
When I would execute the Procrustes ANOVA, I complete the
classifiers boxes like this :
Individual : from dataset
Side : none (I work with object asymmetry so I do not have any choice)
Error 1 : image
Additional main effect : geography.
My results are not good, the ANOVA is not the one that I expected.
I do not understand the results for the freedom degrees and for F.
So I would know if there is a kind of "fluctuating asymmetry analysis
step by step" or anything like that which help me to understand the
MorphoJ program.
Any help is great.
Thanks.
Marion.
