I am trying to use the Tiff(*.tif, 'w') function to save a tiff with multiple frames/slices. The code that I have works, but takes a while to run, especially when I try to use it on 400+ slice tiffs. I have only been able to save multislice tiffs using this rather clunky set of for loops. If I try to write the entire thing at once, I end up with a one slice tiff file that contains all of the slices overlaid on top of each other. If anyone has encountered this problem, or knows a solution I would appreciate it.

Here is the code I have:

FileTif='11_7_dimer_1E4_s1_8_20slice.tif';
    InfoImage=imfinfo(FileTif);
    mImage=InfoImage(1).Width;
    nImage=InfoImage(1).Height;
    NumberImages=length(InfoImage);
    FinalImage=zeros(nImage,mImage,NumberImages,'uint16');
    TifLink = Tiff(FileTif, 'r');
    for i=1:NumberImages
        TifLink.setDirectory(i);
        FinalImage(:,:,i)=TifLink.read();
    end
    TifLink.close();
    intFinalImage = int16(FinalImage);
    for numin = 1:NumberImages
            tiffFile = strcat('bksub_', FileTif);
             for numin = 1
                t = Tiff(tiffFile,'w')
                tagstruct.SampleFormat = Tiff.SampleFormat.Int;
                tagstruct.ImageLength = size(intFinalImage,1);
                tagstruct.ImageWidth = size(intFinalImage,2);
                tagstruct.Photometric = Tiff.Photometric.MinIsBlack;
                tagstruct.BitsPerSample = 16;
                tagstruct.SamplesPerPixel = 1;
                tagstruct.RowsPerStrip = 16;
                tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky
                tagstruct.Software = 'MATLAB';
                t.setTag(tagstruct);
                t.write(intFinalImage(:,:,numin));
                t.close();
             end
             for numin = 2:NumberImages;
                 t = Tiff(tiffFile, 'a');
                 tagstruct.SampleFormat = Tiff.SampleFormat.Int;
                 tagstruct.ImageLength = size(intFinalImage,1);
                tagstruct.ImageWidth = size(intFinalImage,2);
                tagstruct.Photometric = Tiff.Photometric.MinIsBlack;
                tagstruct.BitsPerSample = 16;
                tagstruct.SamplesPerPixel = 1;
                tagstruct.RowsPerStrip = 16;
                tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky
                tagstruct.Software = 'MATLAB';
                t.setTag(tagstruct);
                t.write(intFinalImage(:,:,numin));
                t.close();
             end
         end
