The current stream actually does not run with fixation -- all the fmri data need to have wedge or ring stimulation. The design matrix is just a bunch of sines and cosines, nothing fancy. Jeff Phillips wrote: Hello all, I am performing my first retinotopy analysis, and I'd like to get some mo

Hello all, I am performing my first retinotopy analysis, and I'd like to get some more information about the model created by paradigm files in the retinotopy analysis. Specifically, I am unsure whether to include or exclude fixation periods from the ends of my retinotopy runs. I imagine the ana
