Hi, 

I collected landmarks and semilandmarks on two curves. I slide semilandmarks in TPSRelw. I want to do Partial Least Square between the two curves. I performed PLS in two softwares: MorphoJ and TPSPLS. I detected that the adjusted coordinates with both softwares make the PLS are very similar. However, the final results I get are completely different . In TPSPLS I have a PLS 1 with a correlation of 0.4  (including or not including the uniform component) while MorphoJ PLS 1 is close to 0.9. I wonder why I get such different results if coordenates adjusted on both programs are doing the analysis are very similar.

Regards, 

Marisol
