Since this is GUIDE, we'd also need the BrainMRI_GUI.fig file that goes with this.
That said, I don't know how you're getting any output. As given, the code won't even run since you've defined two different functions with the same name. (Line 629, 648) Not sure what's going on there.

Putting both @Image Analyst and @DGM's very valid points aside for a moment;
If every output is negitive, is the dataset ballanced? i.e. if there are 1000 training observations, but only 10 are true positives (tumors images with matching clinical lable), it would be very easy to train a "always no tumor" output.
