Dear SPMers, Modeling one single design for each subject should be equivalent to modeling several subjects in one single model. However, the results for the same subject are different between both procedures. Which one is right? This occurs with SPM5 last update and Matlab R2006b. Besides, the display above the design matrix indicating which conditions were calculated in each contrasts are displayed only over the first three subjects and not throughout the whole design over all subjects, as expected. This occurred when I performed the contrasts in the multiple- subject model, employing the repeat contrast in all sessions/subjects option. Should I ignore this display and believe that the right conditions of each session are taking into account or there is really a problem? I appreciate your help Selene Cansino ***************** Professor Selene Cansino, Ph.D. Laboratory of NeuroCognition Faculty of Psychology National Autonomous University of Mexico Av.
