Hello Fiona, I do not think it is coming from spm12 but from the change since Matlab2014b (?) which can produce low-level graphics issues. I have not the exact fix for you but you can try: - Quick and dirty: change the values by hand in the art.m file (see after the line % Default values for outliers, e.g. z_thresh, mvmt_thresh, etc. parameters). - Slow but better !: https://fr.mathworks.com/help/matlab/creating_plots/resolving-low-level-graphics-issues.html https://fr.mathworks.com/matlabcentral/answers/157894-resolving-low-level-graphics-issues-in-matlab-r2014b Hope this will help !
