How can I convert multiple individual .tif files to a single .tif stack

I am currently writing some code to convert each frame of a .avi file to a .tif file, but I would also like to store the resulting frames as a single file, i.e. a tif stack.

The imwrite feature 'WriteMode', 'append' is not working (and also not giving an error).

Below is the segment of code:

obj = VideoReader(currAVI); vid = read(obj); frames = obj.NumberOfFrames; mkdir(nameString); writeFolder = strcat(currFolder,'\', nameString); cd(writeFolder);

    for x = 1 : frames

        imwrite(vid(:,:,:,x),strcat('frame-',num2str(x),'.tif'), 'Compression', 'none', 'WriteMode', 'append');

    end

Have you tried this: https://fr.mathworks.com/matlabcentral/fileexchange/35684-multipage-tiff-stack

I ended up writing the first frame to tiff outside the loop and then selecting 'overwrite' and 'append' within the loop and that got it to work.

I really don't know why the usual WriteMode' 'append' name pair argument didn't work, but hey a fix is a fix.

Thanks for your suggestion in any case

Hi Joe,

Asumming you would like to store the frames of your .avi file in a single single stack of .tif file, but your facing issues in executing the same.

This is because you are using different filename (strcat('frame-',num2str(x),'.tif')) for each of the file in your 'imwrite' command.

 imwrite(vid(:,:,:,x),strcat('frame-',num2str(x),'.tif'), 'Compression', 'none', 'WriteMode', 'append');

I would suggest you to use only one name for all the frames instead of multiple names.

You can try replacing the above line of code with the following line:

imwrite(vid(:,:,:,x),'sample.tif', 'Compression', 'none','WriteMode', "append");

I hope this will help in reslolving your quries!
