Error during Greyscale tiff image conversion to RGB tiff image

Hello everyone, I need your kind help.

I'm working on my thesis regarding deep learning techniques and during the process of conversion from greyscale image to RGB image, I got an error.

I saved these images as geotiff from Snap and now I need to put them as input to Mask R-CNN.

However, Mask accepts only RGB images.

Following, the code I wrote:

%% RGB Data Conversion

d = uigetdir(pwd,'Select the Dataset Folder');

srcDir = dir(fullfile(d,'*.tif'));

for i = 1:length(srcDir)

baseFileName = srcDir(i).name;

filename = fullfile(srcDir(i).folder, baseFileName);

s1 = 'RGB';

newfilename = strcat(s1, baseFileName);

grayIm = imread(filename);

RGB = cat(3, grayIm, grayIm, grayIm);

t = Tiff(newfilename,'w');

tagstruct.ImageLength = size(RGB, 1);

tagstruct.ImageWidth = size(RGB, 2);

tagstruct.Photometric = Tiff.Photometric.RGB;

tagstruct.BitsPerSample = 8;

tagstruct.SamplesPerPixel = 3;

tagstrut.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;

tagstruct.Software = 'MATLAB';

setTag(t, tagstruct);

write(t, RGB);

close(t)

end

and the error I got:

Error using tifflib

Illegal value (0) for PlanarConfiguration.

Error in Tiff/writeAllStrips (line 1938)

meta = tifflib('retrieveMetadata', obj.FileID);

Error in Tiff/write (line 1486)

obj.writeAllStrips(varargin{:});

Error in MASK_R_CNN (line 26)

write(t, RGB);

Can someone help me?

Thank you for your availability.

You have a small typo:

tagstrut.PlanarConfiguration

you missed a c, you wanted

tagstruct.PlanarConfiguration

Oh my God, I'm pretty embarrassed about it. Thank you so much!
