RE: Different sessions as different conditions?
Hi Kaylah,
The "Effect of [condition]" regressors represent the shape of the expected BOLD response associated with each condition (block timeseries convolved with the hemodynamic response function). You should typically include those in the 'Confounds' list in Denoising, so that those effects are removed from the BOLD timeseries of interest before proceeding. If you do so they will then not appear listed as potential sources in the first-level analysis tab (any ROI, condition effect, or first-level covariate that is not included in the 'Confounds' list is passed as a potential seed for seed-to-voxel or ROI-to-ROI first-level analyses).
Hope this helps
Alfonso

Hi Alfonso,
We have one scan with multiple blocks. We inputted it into conn similarly to what you advised above. When looking at the second level analysis, I see under "Targets" multiple "Effects of...[each condition]". What exactly does this mean?
Thanks!
