Hi Carmelo
Thank you for your response. Yes I know that Matlab is a very useful software,
perhaps you can share with me your code or procedures in Matlab??. Purposely do
you know if it is possible to obtain the z coordinate if I only have the x and
y coordinates??. I mean it is possible perform a reconstruction of the z
coordinate of a landmark using the information on the x and y coordinates ??
thank you
best
Miguel

Hi Miguel,
Normally these days when I have to do these reflections I use Matlab.
For an older paper (Fruciano et al. 2011 - It J Zool) I think I used
LMedit from the IMP package (it's been a while now).
However, if your data is only on half of the face, I would perform the
analysis only on half the face and then use reflection across a
symmetry axis only to display the results...
Best,
Carmelo
