Loading and processing multiple images using uigetfile

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;
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
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)
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

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.
