Thank you for your replies Dr. Rohlf and Dr. Cardini, I checked and in version 1.72 the .nts and .tps files (Scaled specimens) have the same coordinates... Regarding the problems I was having, I realized that they were due to the *Boas coordinates* (Procrustes coordinates*CS) being *selected by default even if the Procrustes option is checked*. So the Scaled specimens file was actually equal to Boas coordinates*CS. That's why when redoing the GPA in MorphoJ the CS values were so different, they were approximately equal to CS*CS.
Dr. Rohlf, thank you for your dedication to constantly improve the Tps software.
