Hi everybody! I just started to play with 3D GMM but I have some questions. Not sure I am doing the right things. I landmarked (anatomical+curves) the left side of six skulls and I would like to get my final matrix to do my analyses. I defined my landmarks and subsampled the landmarks on the curves. Then I patched the landmarks on all my specimens. So, for now, I have my 6 specimens with the landmarks at the right place on them.
And here begin the troubles… I wanted to relax and slide the landmarks to minimize bending energy but I think the surfaces are too different because unless I use a stepsize of 0 (meaning that this command is useless I think) in relaxing and sliding commands, the landmarks do not fit the curves anymore. #relaxLM(patched[,,i], rbind(atlas[["landmarks"]],atlas[["patch"]]), slidings, outlines = curv, surp = surface, sur.name = NULL, mesh = ply2mesh(paste("./ply/",meshlist[i],sep="")), tol = 1e-50, deselect = FALSE, inc.check = F, iterations = 50, fixRepro = TRUE, stepsize=0) #slider3d(relaxedtemplate4, slidings, outlines = curv, surp = surface, sur.path = "./ply", sur.name = NULL, meshlist = paste("./ply/",meshlist,sep=""), ignore = NULL, sur.type = "ply", tol = 10e-50, deselect = FALSE, inc.check = FALSE, recursive = TRUE, iterations = 3, initproc = TRUE, pairedLM = 0, mc.cores = 4, fixRepro = TRUE, stepsize =0) I tried to play with the tolerance and/or the bending=TRUE but nothing has changed. What could I change in these commands? Are these steps mandatory to analyse the shape? Any comment, advice and suggestion is more than welcome! Thanks a lot for your help.
