Hi FreeSurfer users, I have some resting state data that I preprocessed and conducted first level analyses using the flag -no-con-ok. Since no ces.nii.gz or sig.nii.gz is createdcomes up because there is no contrast, I'm wondering if it's possible to conduct functional ROI analyses with the data processed this way. Or would I have to do ROI analyses with the data processed in a seed-based manner where the seed is the "contrast"? Best, Talia
