Dear Renata,
if you're looking for point-and-click solutions, three options come to
my mind in this moment (I may be forgetting some others):
- SHAPE by Iwata and Ukai http://lbm.ab.a.u-tokyo.ac.jp/~iwata/shape/
- NTSYSpc (which, if I remember correctly, also includes a very useful
routine for the inverse transformation)
- PAST
The latter two obviously do much more than just elliptic Fourier
analyses, by they are point-and-click and comprise routines for that.
In any case, you may want to check carefully their help files (and
original publications) as I'm quite confident there are some differences
in what is happening "under the hood" across these three programs (for
instance in the way they try to remove non-shape variation due to
rotation and size).
I hope this helps,
Carmelo

Dear Morphmet community,
I am currently working on 2D-GMM of archaeological stone artefacts, and
I would like to ask what software you would suggest for EFA (Elliptic
Fourier Analysis) to run 2D-GMM analysis. I am still not very familiar
with R, so other software suggestions would be best.
Thanks a lot.
Best regards,
Renata Araujo
