Dear Eugenio,
Thank you very much.
After executing that script, I can obtain the convolved time series in convreg file. Based on the description "These sequences were convolved with a hemodynamic response function and entered into a regression analysis against the fMRI data", how can I then enter these convolved time series data back into SPM model specification gui to isolate brain activity correlated with, in the case of the original paper, expected reward values and PEs?
