Dear SPM list, We are getting an error message while trying to display results. It appears after opening SPM.mat , choosing contrast, choosing "mask with other contrast": "no", "title for comparison": "title_name". Could you please help us to understand what the problem is and if it is possible to make this SPM.mat file work again.
