I research 3 D volumetric brain tumor image using Brats 2016 and 2017 dataset. I will find dice coefficient .But following error

Error using dice (line 117)

Expected input number 2, B, to be one of these types:

logical, double, categorical

Instead its type was uint8. In dataset, is groundturth image labelTr?.

How do you expect it to determine the union and overlap with grayscale images? You have to segment them into binary images first.
