Four possible error conjectures with SPM in MATLAB

Abstract

Flanker tasks are mainly supposed to have activation signals on the prefrontal regions and anterior cingulate cortex (ACC) because this assignment requires immediate actions from participants after seeing unique signs. The SPM in MATLAB is used to process the data of activation signals of brains from flanker task data collection. This process has four steps: preprocessing of all the subjects, first-level analysis, second-level analysis, and Region of Interest (ROI) analysis. After all the steps, the final graph should show black spots representing the activation signal on the prefrontal and anterior cingulate cortex regions. However, the spotted area differs from the areas in the proper graph, indicating the errors during processing each subject in flanker tasks in this assignment. There are four conjectures of error steps after reviewing the wrong result
