Hello everyone, I have a couple of questions about tpsRelw and MorphoJ that I hope someone could answer.
I performed a GPA with sliding semilandmarks in tpsRelw v 1.71, after that, my intention was to proceed with the analysis in MorphoJ. So, I saved the "Scaled aligned specimens" file in order to import the shape and size information in MorphoJ. But I found something odd at this point. I saved the "Scaled specimens" in .tps and .nts formats and the values of the coordinates are different in the two files (i think this may be a bug). The coordinates in the .nts file seem to make more sense, however, I don't understand where they come from. I thought they simply would be equal to the coordinates in the "aligned specimens" file multiplied by the centroid size values. Could someone explain this to me? Then I continued using the .nts file in MorphoJ. I did another GPA and exported the centroid size values to compare them with the ones I got in tpsRelw. They are very different and I don't understand why. I would appreciate your comments on this. I attach the files I mentioned in case anyone wants to take a look at them. Best, Felipe Garzón GPA parameters used in tpsRelw: - PCA align reference - Slide semilandmarks by Chord-min BE - Scale aligned---1 - Projection---None - Alignment---Procrustes -- Felipe Garzón Agudelo Biólogo Universidad Nacional de Colombia -- You received this message because you are subscribed to the Google Groups "Morphmet" group.
