Trouble with 3D geometric morphometrics/PCAs


New Member
Hi all,

I've been doing some 3D shape analyses using landmarks and analysed the resulting data using PCAs. I'm not very familiar with all this so I was wondering if there's a way to superimpose the landmarks on my PCA plots.
I'm guessing that I'd have to start with figuring out which raw coordinates from the output belong to which landmarks? If so, how would I do that?

Any help would be much appreciated! :)
