You may want to use uiwait() so the message pauses there and waits for the user, and does not keep barreling along with the rest of your code, as just a plain msgbox will.

message = sprintf('Disease identified as %s', DiseaseIdentified{1});
uiwait(warndlg(message)); % Waits, and displays exclamation point.

or, if it is normal

uiwait(helpdlg(message)); % Waits, and displays info text balloon.
uiwait(msgbox(message)); % Waits, and displays no icon at all.

Just put it in a while loop until they get it right. Warn them like this:

message = sprintf('Error: you entered %d when you should have entered a number in the range [0,99].', theirNumber);
uiwait(warndlg(message));

In general for a try/catch you can try this:

function blahblahblah()
  try
    % Some code that generates an error.
  catch ME
    message = sprintf('Error in blahblahblah():\n%s', ME.message);
    uiwait(warndlg(message));
  end

uiwait(msgbox({'line1';'line2';'line3';'line4' } ,'About !','modal'));
