Hi,

I was wondering whether it is possible to load multiple images using uigetfile. I know how to do it with one file:

[FileName, FilePath]= uigetfile('.TIF','Select File to Open'); 
            
            %If user does not select file
            if [FileName,FilePath] == 0; 
                return; 
            end
           
            I_M = imread(fullfile(FilePath, FileName));

But I'm wondering how I can use the multiselect feature with uigetfile

            [file,path] = uigetfile('*.TIF','Select One or More Files','MultiSelect', 'on');

And then read multiple images using imread that runs with a for loop, something like this:

            for count=1:total_images_selected
    images{count}=imread(%not quite sure what to put here);
    %Some analysis afterwards that basically sums the matrix values in a processed image
end

Any help would be appreciated!

Looks like you almost had it, but just to fill in the "%not quite sure what to put here" part:

[file,path] = uigetfile('*.TIF','Select One or More Files','MultiSelect', 'on');
if isequal(file,0)
    return
end
total_images_selected = numel(file);
images = cell(1,total_images_selected);
for count = 1:total_images_selected
    images{count} = imread(fullfile(path,file{count}));
    % analysis
end

Thanks so much!

Chances are you don't need to save all your images in a cell array, which could eat up all your memory. You can probably just process them right then and there in the loop.
