Hi Freesurfer Team,
For a given group, I want to look at the covariance patterns between thickness and PET. Within Freesurfer, what are some general workflow tips on how I could go about performing PCA (within modality) or joint ICA analyses looking at the covariance patterns across modalities? Is the -pca flag a good starting point?
Any feedback is appreciated!
Thanks a lot.
Best Wishes, Elijah
