Loading GPA results from geomorph into Slicermorph?

Hi community,

I have created a dataset of 499 pseudolandmarks for 107 bones using ALPACA. I compared the GPA+PCA results from geomorph and Slicermorph and noticed that geomorph describes ~10% more variance along PC1, possibly due to my correction for the ‘sliding’ factor.

Now, I want to explore the data generated in geomorph within Slicermorph. How can I import these data, and in what format? I noticed that Slicermorph’s GPA results generate multiple .csv files—do I need to create similar files to successfully import my data into Slicermorph?

I hope I’ve explained this clearly. Thanks in advance for any help!

Please look at this example. At this point you we “hack” the GPA module’s “Load an existing analysis” feature to bring results from R and geomorph specifically:

basically all you have to do is to point out the variables that store aligned coordinates and PCA results from geomorph and pass it to function called geomorph2slicermorph2.
