Hi All, I'm trying to run a PPI analysis and I keep getting an error. After extracting the ROI and creating the PPI structure for the PPI.mat file, I get the following error: ??? There is no 'FitBoxToText' property in the 'textbox' class. Error in ==> spm_peb_ppi at 522 set(h,'String',str,'FitBoxToText','on','EdgeColor','none'); What does this error mean???? Thanks! Fred
