Subject: permutations in TPSRegr and asymmetry in pictures

Dear Morphometricians,
please, has anyone got any experience with the different options for
permutation tests in TPSRegr?
I did not manage to find an example in the help file but I may have missed
it and would really like to find something like the detailed protocol Jim
describes for the test of common slopes etc.
A second unrelated question. I was wondering how studies of asymmetries
might be affected by using pictures of 3D objects (e.g., human faces).
I can easily imagine biases that could spuriously introduce DA in the data
and may not be obvious to detect. Even without any systematic error, I
wonder whether the 2D approximation of a 3D object may affect FA.
Thanks for your help.
Cheers
Andrea
