Question

I am trying to combine 4 separate bands into a multispectral image (960x1280x4).

I have 4 cell arrays of 1315x1 each and I am using 'cat' function to combine.

test=cell(1315,1)
for i=1:1315
    test(i)=cat(3,G{i},R{i},RE{i},N{i});
end

I am getting error as "Conversion to cell from uint16 is not possible."

Please help

How does your code define G, R, RE, and N?

Green band, red band, Red Edge band and NIR band. So each of them is a 1315x1 cell array

You need to use braces to put each created image into a new cell. See the FAQ to get a good, intuitive feel for what a cell array is http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

Try this:

numImages = length(G);
allImages = cell(numImages , 1);
for k = 1 : numImages
    allImages{k} = cat(3, G{k}, R{k}, RE{k}, N{k});
end
