How do I use sliceViewer with RGB images?

8 views (last 30 days)
1 have a number of 2D RGB image arrays (slices), each with dimensions (x,y,3).
I have collated them in an array of teh form (x,y,3,nslice). Where nslice is the number of slices. I am trying to vew these colour slices using sliceViwer but it isn't working. If I try and view just one slice I get 3 images in the figure, one for each of R,G abd B. If I have more than one slice in the array I just get an error:-
"sliceViewer requires 3-D grayscale(MxNxP) or 3-D RGB volume(MxNxPx3) with no singleton dimensions."
Trying to re-arrange the data to the foramt suggested doesnt work and doesnt make sense really.
Can anyone help?

Try using the permute function to swap your 3rd and 4th dimensions.
newRGB = permute(RGB,[1,2,4,3]);
