I have run 1st level group-ICA analysis and there are a few components that I would like to use as network ROIs in a seed-to-voxel analysis. I have saved the 3 ROIs of interest as parcellation ROI files, added the 3 components as ROIs in the setup menu, but they don't show up as a potential ROI in the 1st level analysis. Am I doing this incorrectly? Any help would be much appreciated.

Thanks
