Re: [Freesurfer] PCA on PET / Thickness in Freesurfer

For within modality, you can add --pca to mri_glmfit (run it with --help to get more info). We do not have ICA tools in FS.

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
