Dear morphogeometricians Hope you are well. I ran a GM analysis using 3D landmarks obtained in aviso for mice skulls and I used shapes and Morpho R packages. I’m trying to obtain deformations (so-called warping or morphing) for the negative and positive PC shape changes of a 3D model. However, I can’t find a method to do this in R. I realized Morpho allows to obtain a 3D warp movie but I’m not sure that method is the one I’m looking for and in Geomorph there is a function (warpRefMesh) to create warpings but using just the mean shape (ref) and a specific individual not for PCs. I have used MorphoJ and Landmark IDAV to do this in the past but since I’m using a lot of semilandmarks it is a bit difficult to digitize my dataset in Landmark to do the warpings. I uploaded my dataset in Morpho, and by using the function write.pts I was able to transform the 3D coordinates in a .PTS file. Despite that the file uploads correctly in the corresponding mesh in Landmark I don’t know why I can’t run the method explained in the MorphoJ user guide. It seems the landmarks uploaded in Landmark must be obtained directly in Landmark IDAV and not using the method described above. In any case, I want to obtain 3D shape deformations of a 3D mesh according to PC scores in R but I was not able to use any of the methods mentioned above in Morpho and Geomorph. Thanks in advance for any help with this issue.
