I seem to have encountered a similar error. With CONN16b. I've run seed-voxel and ROI-ROI analysis and went to add voxel-voxel analysis. When I try to run the first-level voxel-voxel analysis I encounter the error: "No Conditions Found. Please re-run first-level analysis," which I've attempted to do with no luck. This same error appears when I attempt to access any level second level results. I'm attempting to run only a group-ICA analysis. Though it looks like I need to re-run my first level ROI-ROI and seed-voxel analyses.

I've also noticed that I'm able only to run both seed-voxel and ROI-ROI OR voxel-voxel, and not all three in the first level step. 

Any thoughts?
