*Error using writetif (line 40)
Writing TIFFs with 10 components is not supported with IMWRITE. Use Tiff instead. Type "help Tiff" for more information.
Error in imwrite (line 472)
feval(fmt_s.write, data, map, filename, paramPairs{:});*

It is not possible to imwrite() TIFF with more than 3 channels. You need to use the Tiff() class and choose one of the several different ways that TIFF can store additional data.
