Hi Jade, I am also a masters student attempting to use MorphoJ and am having a difficult time with the missing data. I collected 3D landmarks for a cranial asymmetry project and cannot get MorphoJ to run. It keeps giving me an error message. Did you happen to figure out what the issue was? I would truly appreciate any advice you might be able to share.
