how to project an image stack in time dimension?

I have a tif format image stack which I upload using below script. Now I want to get an image which is the addition of all images together. This will help me to see the track that an object moved in time (third dimension). I would appreciate a help with this.

[fName, pName] = uigetfile('*.tif');
imageD1 = imread(fullfile(pName, fName));
imageD1=double(imageD1);

info = imfinfo(fName); num_images = numel(info);

dummy=1; for i=1:num_images imageData1(:,:,dummy) = imread(fullfile(pName, fName),i); dummy=dummy+1;

end

It should be as simple as:

%%I just do this for all files in the same directory, you'll have to fix file-finding...
fNames = dir('*.tif');
totD = 0;
for iFiles = 1:numel(fNames)
  imageD1 = imread(fNames(i1).name);
  imageD1 = double(imageD1);
  totD = totD + imageD1;
end

Thank you, perfect. Only a small amendment:

imageD1 = imread(fNames(iFiles).name);

any Idea about how to save the figure as a tif file;

these didnt work for me:

Name='rExFil_1';
imwrite(totD, '16bit.tif'); 
or
imwite(fNames.name)
or
imwrite(uint16( Name+min(min(Name)) ), 'Tm2ZeroSDx2Sig_ch1.tif', 'tif','Compression','none')
