Hello. I have never posted here, but I searched about the problem that I am facing and I have not find a topic. So I am posting now.
I digitalized 4 LM and 160 semiLM (4 curves) with TPSDig to analyze the pronotum of six beetle species (>400 specimens) and transformed the semiLM in LM on TPSUtil. So I had 164 LM – I also did NOT aligned them - . I opened the file on MorphoJ and did PCA, CVA and discriminant analysis of the pairs. Everything went apparently ok. (→ I know that there are many problems because the exaggerated number of LM). graphic: <https://www.ibb.co/ypcbGb8> But now I know I had too many LM. So I deleted many of them on TPSUtil (I just took the TPS file of the 164 LM and deleted half of them, creating a new TPS file). Again, I did not aligned it. I did the same analysis on MorphoJ. The PCA and the CVA were ok, but the discriminant analysis did not work. I tried everything. graphic: <https://www.ibb.co/j5hQq59> So I gave up and did the sliders of the 164 LM, even knowing it wouldn’t be good for the subsequent analysis. So I used the TPSUtil and did the sliders, following the manual. It took some time but I could save the aligned and scaled aligned data from TPSRelw. But again something went wrong graphic: <https://www.ibb.co/X8WdkGb> Does someone know what might be the problem? -- MORPHMET may be accessed via its webpage at http://www.morphometrics.org --- To unsubscribe from this group and stop receiving emails from it, send an email to morphmet+unsubscr...@morphometrics.org.
