Affectiva Q sensor support for Ledalab

% Optionally reads additional marker data from another csv file (prompted)
% The dialog suggests a file fullpathname + 'm.csv'.
% The Q software forces a .csv ending to the given filename and the 
% following trick makes it easier to name the files accordingly:
% Select the exported datafile, append 'm' to the filename and click save. 
% Now you'll have a datafile.csvm.csv file.

    % Marker csv columns: Dataset,Marked on Device,Note,Start,End
    % Lines with the word Dataset are ignored (treated as comments)
    markers = textscan(fid, '%s %s %s %s %s', 'HeaderLines',0, 'Delimiter',',', 'CommentStyle','Dataset');

            markedOnDeviceId = markedOnDeviceId + 1;
            event(markedOnDeviceId).name = strrep(markers{1,3}{line}, '"', '');
        % New marker added with the Q software (lacks a data row with Event col set as 1)
        else
            eventId = eventId + 1;
            event(eventId).time = timestamp2sec(markers{1,4}{line}) - start;

I'm a bit confused about how to include this in running data through Ledalab. What should this output for me? I don't see the utility of a .csvm.csv file if Ledalab doesn't support that either. Please correct me
