I want to process a number of images for data analysis. If one of the images causes a matlab error, I want the program to display a message but to continue with the analysis of the following images. So it would need to continue with the next iteration of a for loop. Is this possible and how would I do this?

Thanks, Christine

You could do something like

for ii = 1:n
  try
    % your code
  catch ME
    warning('Something happened');
  end
end

Great, thanks a lot. This works fine:

 for number = 1:number_of_images
    try
        %image analysis program
    catch ME
        disp('mistake in picture number'); disp(number);
    end
 end

In this case you do not need to catch the exception object (ME). You might want to check ME to make sure it was because the there was a mistake in the picture number and not some other error.
