Hi SPM users, My work consists on substracting images on ImCalc, but, what I need is to know what the values of the differences between the images and each difference or value correspond to which image and I can't do that on Imcalc. I also tried using 'DATA MATRIX' in Imcalc' but every time it gives me an error: 'Error running job: Error using ==> spm_incalc Can't evaluate "i1-i2". Thanks in advance, Kerlany Pereira.
