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
