How to create a montage from a 3D subvolume?

I have created a 3D subvolume within a 3D image. I would now like to display that subvolume as a montage. It appears that I need to save the subvolume and then call it using the montage command. However, I cannot figure out how to successfully save the 3D subvolume. Please let me know if my question is unclear or if more information is needed. Thank you.

No, you don't need to save it. From the doc,

montage(I) displays all the frames of amultiframe image array I in a single image object. I can be a sequence of binary, grayscale, or truecolorimages. A binary or grayscale image sequence must be an M-by-N-by-1-by-K array. A truecolor image sequence must be an M-by-N-by-3-by-K array.

So, my array (subvolume) is 512 X 512 X 6 array. It appears that I cannot simply use the command: montage(subvolume);

I get the errors: Error using imageDisplayValidateParams>validateCData (line 117) Unsupported dimension.

Error in imageDisplayValidateParams (line 31) common_args.CData = validateCData(common_args.CData,image_type);

Error in imageDisplayParseInputs (line 79) common_args = imageDisplayValidateParams(common_args);

Error in imshow (line 220) [common_args,specific_args] = ...

Error in montage (line 137) hh = imshow(bigImage, displayRange);

Do I need to rearrange this array in order to use montage?? Thank you!

I jumped the gun on asking a follow-up question. It appears that the following line of code solves my problem. Thanks!

 montage(reshape(SubV,[size(SubV,1), size(SubV,2), 1, size(SubV,3)]),'DisplayRange',[]);

Brilliant!
