I have two niftii file, one is for the skull and one is the mask of fracture. How can I overlay the mask on the skull volume? I want to analyse it slice-by-slice of the masked skull for my project

Are the dimensions of the 3D mask the same as the 3D volume and aligned? If so and the mask is binary, you could multiply the volumes together.
Did you want to display a color version of the mask? Could make mask a color image. Then you could display it ontop of original image (T1 sequence?) using the hold function. You could change the AlphaData value to make it transparent.

Hi,
I tried to do the first step (multiplying the 3D volume and mask (binary)) using mtimes but it result as Mtimes (*) is not fully supported for integer classes. At least one of the argument must be scalar
I imported the image using niftiread which result in uint8 file (mask) and uint16 file (3D volume).
Could you help solving this problem? Thanks
