Tiff (tifflib) append reaching limit of frames

Hi Community

I have a function that export a 3D matrix to a tiff file.

Its working well, but when appending the submatrix 4096 and error is shown

Error using tifflib

Unable to write strip #1.

Error in Tiff/writeAllStrips (line 1978)

tifflib('writeEncodedStrip',obj.FileID, stripNum-1,imageData(row_inds,:));

Error in Tiff/write (line 1486)

obj.writeAllStrips(varargin{:});

Error in exportToTIF (line 52)

write(t,single(imgdata(:,:,i))); %% When i = 4096

Have you seen that behaviour before?

Thanks a lot

Here's the code

% Config. Tif
tagstruct.SampleFormat = Tiff.SampleFormat.IEEEFP;
tagstruct.Photometric = Tiff.Photometric.MinIsBlack;
tagstruct.BitsPerSample = 32;
tagstruct.SamplesPerPixel = 1;
tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
tagstruct.Software = 'MATLAB';
tagstruct.ImageLength = size(imgdata,1);
tagstruct.ImageWidth = size(imgdata,2);

% Writting first frame
t = Tiff(selpath + folder + fileName + ".tif",'w');
setTag(t,tagstruct)
write(t,single(imgdata(:,:,1)));
close(t);

% Appending the rest
for i = 2 : size(imgdata,3)
    t = Tiff(selpath + folder + fileName + ".tif",'a');
    setTag(t,tagstruct)
    write(t,single(imgdata(:,:,i))); % Here the error when i = 4069
end
close(t);

I am not clear why you construct t in the loop? It does not appear to depend on the loop variable?
