I am trying to load previous PCA results into slicer but it is not working even after uploading the JSON file that I saved. I even tried restarting slicer multiple times but it still doesn’t work, how can I resolve this issue?
Thank you

Is the PCA from GPA module of SlicerMorph? If so, you will get faster response next time if you tag your question as SlicerMorph.
Are you using the Load Previous Analysis button? If so, make sure you are using the latest version of SlicerMorph. There was a bug in this function, which got fixed a few months ago.

I was using the Shape Population Analysis module in SlicerSALT. I will try using SlicerMorph instead though, thank you.
