At what line does my parfor loop error?

Hello World,

I am using the parfor command to run a job on multiple processors. I am running the same function on over 100 files and the function works for most files but not all. I am getting an error which indicates at what line the error occurred in my function and sub-functions but does not indicate on what file the error occurred.

Is there a way I can have matlab output the more information about where the error occurred?

Example:

-------------------------

% Run_all_files_script.m

parfor fileNumber = 1:10

        main_function(FileName(fileNumber));
end

-------------------------

example of error:

 "Error in Run_all_files_script (line ##) 
    parfor fileNumber = 1:10"

Is there a way I can output what "fileNumber" is equal to at the time of error?

Thanks,

-Tom-

parfor ii = 1:100
    try
        process_file(ii)
    catch
        error(['Error in File ' num2str(ii)])
    end
end

Try/catch is probably the easiest.
