% reward jpeg for version1 from isaac
% get a few random people to do test runs 

% 9 Oct 2003
% Addressed question at end of yesterday's effort, see below.
% Add column descriptions at top of text file output, checked it
% out in Excel and tab delimiters make it look good.

% 8 Oct 2003
% Added many comments
% Added click sound for when wheel stops and shifted cashreg and asterisk sounds
% to present simultaneously with their screens.
% Encapsulated novel JPG and WAV initialization code for version 3 in an
% if-statement, added a diagnostic that finds the longest WAV file, and
% made the novel list be multiple shuffled batches of what is available.
% NEED TO ASK IF ALL SHOULD BE USED ONCE BEFORE ANY REPEATS? (Two options
% available below.)
% Q PRESS QUIT NOT MOUSE SENSITIVE? (Turns out that left-mouse button is
% part of KbCheck matrix, so q-press code unchanged and other
% keyboard/mouse code simplified to just keyboard.)

% 24 Sep 2003 notes
% Added q = q/max([abs(max(max(q))) abs(min(min(q)))]) to keep all sounds
% in same volume range and especially to make soft ones louder.

% 17 Sep 2003 notes
% Add max pause before automatic spin
% Version 3, will have index of maybe 100 images and sounds to use.

% 10 Sep 2003 notes.
% 1. Ensure that at least six spins between asterisks,
% but natural randomness aftre sixth.
% 2. Adjust to key and mouse click.
% 3. Initial screen for investigator control (backtick key).
% 4. Versions 2 always ends on 10 except asterisk every eighth trial.
% Number reward screen will simply count "Trial = 1", "Trial = 2", "Trial = 3"...
% until asterisk and then reset, no $$$ indicator.
% 5. Version 3.
