For an analysis of shape, the Procrustes step eliminates differences due to orientation, position, and size. Not necessary to put the bones in the same position although it may look better for publication. To study allometry, you may wish to include a ruler of some other standard object to be able to retrieve the absolute scale.__________________F. James Rohlf, Distinguished Prof. Emeritus Dept.

If so, what sort of standardization would you like to complete on the photos?JamesOn Tuesday, February 10, 2026 at 8:28:51 PM UTC-5 [email protected] wrote:Hello everyone I need some help.We are making a device to padronize the photos to use in 2D Geometric Morphometric.But we can't find anything get inspiration from, so we are making one by zero.Have anyone ever made something like this before?
