Dear SPMers,I tryied to create MTR maps using imagecalc, but something it's wrong and I don't know if it's the formula or the type of image.I used the formula ((i1-i2)/i1)*100.The only calc that I can do is i1-i2.And the format I used the same as the input, int16.Can anyone help me creating this MTR maps?Thank you.Lucas Lessa.
