If you just want to compare shapes (the usual application) then the scale does not matter.

Hi,

 

A question, is the scale is of importance in elliptical fourier analysis (EFA)?, can I use bone outlines while the scale bar is not the same?. If no, how can I define a scale for this kind of analysis?

 

Thanks,

Dan
