RE: ANCOVA with 3 groups
Hey Liron,
The Import Results button can be found when in the seed-to-voxel explorer, and it'll create a second-level covariate of the connectivity values shown on the screen for your particular seed-to-voxel result (for the particular parameters selected: one-sided vs two-sided etc, p-value and cluster threshold etc; I'm using v14 though). This covariate appears in the second-level covariate tab of the Set-Up step, and will be ready for selection on the Second-Level preview results tab.
Best,
Fred

I'm really sorry, but unfortunately I have to say that I got more confused... First, I'm not sure what you meant by "'display values' or 'import values'"? I know that when I right click at the ROI-level results, I can get the 'export stats' etc, but there I only find subject-level betas, and unless I'm missing something I don't think that's what you meant.
Second, If I understand correctly, you were saying that any combination of two from these three contrast [1 -1 0 0 0 0 0; 0 1 -1 0 0 0 0; 1 0 -1 0 0 0 0 0], actually already represents the third one. The way I see it, this should mean that any combination of two contrast from these three should give the same result, right? However one gives 0.28, another gives 0.29 and the third gives 0.4 (which is the same as the combination of all 3 contrast). I apologize if I'm missing something obvious... this is all new to me.
Again, thank you very much, I really appreciate your help!!
