I am currently working on my Master's thesis project and am trying to find morphological reconciliations for new molecular phylogenies of a certain taxonomic family of crinoids (marine invertebrate sister to sea urchins, sea cucumbers, and sea stars). I am focusing in a certain skeletal piece and have been landmarking 2D images of the piece in TPSDig2 for statistical analysis in R.
I am new to geometric morphometrics (really to statistics in general) and was hoping to get an idea about whether I have chosen the correct tests to perform. I am not in the analysis phase quite yet, but I want to be ready when I am. I have created a list of what general tests I think I need to perform (listed below) and would love any input on anything that seems redundant, unnecessary, or anything I am missing. After coordinates are created and uploaded into R: - Procrustes Superimposition - PCA - bgPCA or CVA (?) - MANOVA - LDA - Hierarchical clustering (to see how it compares to the molecular trees) - Phylogenetic comparison tests to estimate ancestral character states Please advise, thank you Brenna -- 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.
