Marianna, I completely understand that R and other coding approaches can seem daunting. But I agree 100% with Murat, and encourage you and others to steer into the wind! Coding is empowering!
First, a bit of R-coding allows you to improve your data manipulation and curation. This helps with scientific repeatability, compliance with journal requirements (which increasingly require one to submit curated data and scripts to a public repository), and basically enhances and encourages open-source science. But more importantly, coding empowers you as a scientist. By moving to R, you remove yourself from the restraints that exist with canned software, whose options are necessarily limited by the buttons and options that the user has available to point-and-click. In essence, while prepackaged software is easy to use, it limits thinking and creativity by restricting one’s analysis to those options that the software happens to have. The unfortunate outcome of such canned software is that our GM literature becomes filled with many studies of similar analyses: not because those biological topics are inherently interesting per se, but because that is what the software happens to allow. This is the analytical version of what one of my mentors (Larry Slobodkin) once called ‘intellectual painting by numbers.’ I seriously hope that our field can do better now in the 21st century. My message: learning a bit of code breaks this cycle, and frees one to investigate the questions that one actually wishes to explore, not just those for which canned software has already provided. I strongly encourage you (and others) to learn a bit of R, Python, or some other language so that your creative science is not restricted! Best of luck in your journey. Dean Dr. Dean C.

Yes, it will probably take longer, yes it will be somewhat bumpy road initially. But you will be much better set for the next challenge. Graphical user interface applications are good up to a point (for common tasks). And I am telling you as someone who is developing UI based morphometrics analysis. Most often in biology, you will have to customize your analysis to the specific question you are trying to answer. This is best done via scripting in a flexible programming environment (whether that's R or Python or some other language is irrelevant). There are tons of resources and a very supportive community to help you with your challenges. Going forward, all fields of biology will be more computational not less, and the sooner you start warming up to the idea it will be better for your career. Your future self will thank you for that decision. M On Sunday, January 5, 2025 at 5:05:47 AM UTC-8 [email protected]<mailto:[email protected]> wrote: Thanks everyone... I suspected this was the case but wanted to be sure I wasn't missing anything. I'm going to look into using PAST first, since I'm not the most comfortable in R.

One can do the permutations in R. If you have also a main factor, however, it is a bit convoluted to design it (or at least I found only a convoluted way of doing it). You'll find a description in a footnote in Table 1 of https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2527 If you're analyzing symmetry/asymmetry, the 'trick' I used needs to be reworked and may not work but it should be possible to do an equivalent analysis in one of the morphometric packages (morpho, geomorph, not sure about momocs). I am sure a skilled R coder will be able to suggest better ways. Good luck.

Does the Procrustes ANOVA in MorphoJ use permutations? I don't see it as an option, though I see it in regression and in Matrix correlation. I expect that since there isn't an option for it, then it is not a permutation-based test, but it seems so odd that it wouldn't be. I can't find it in the documentation, and I'm convinced it must be there and I'm missing it. If there is something that discusses this, could you kindly point me to it.
