Save a Tiff image to open as RGB with ImageJ

Hi

my question is quite simple but I can't find a way to solve my little problem. How can we save an image in RGB format so that ImageJ opens it as a 'RGB color' image instead of a composite image?

thanks

imwrite(rgbImage, filename);

Oh thanks, I think I should have mentioned a few details however since I'm currently using imwrite and it does not work exactly as I would like. Actually I want to save an image sequence contained in a cell array named "SequenceToExport". This is the code I'm using:

for i = 1:FrameNumber

ExportedName = sprintf('%s%s%d.tif',fileName,'T',i);
                                 imwrite(SequenceToExport{i},ExportedName,'tif','WriteMode','overwrite','Compression','none');
 end

It works fine but ImageJ recognizes the data as 16-bit images. Sorry I don't know the exact terminology I should be using. Thanks!

What is the data type of SequenceToExport{i}? Is it uint16? Or uint8? Whatever it is, ImageJ should recognize it as the same data type.

It's uint16 so it does make sense yes.

Are we done then?

Actually no since images won't open as RGB in ImageJ. I get that they are coded in 16-bit and that the format is right, but I don't understand why all 3 channels are not merged so that ImageJ opens them all at once as 'RGB color'. Thanks for your help.
