I a m working on human skulls fossiles. Therefore there are many missing points and I decided to replace the bilateral points by the symetric (right<->left) points. (Of course this does not solve the problem when the missing points have no symetric and when both symetric are missing.) I am working on 3D data and found only morpheus to partially answer my problem: 1) For each individual I construct the symetric by changing the sign of one coordinate (x, y or z) 2) I import each individual and its symetric to Morpheus then do a gpa of those 2 images (individual and its symetric) 3) I use the consensus, unscaled, for the further work (gpa, pca etc...with the R shapes library of Ian Dryden) on all my skulls Therefore, I am working on completely symetric skulls because all symetric points (right and left) are averaged. I did this procedure one by one, which is a little bothering and working like a donkey. This was possible with my 100 skulls used in my master degree, but no more now with hundreds of Pan, Gorilla, Homo etc... I am now looking for an automatic procedure to do this job. Do anyone know a software that could help ?
