%% v17: 
% edited on 02/19/2017
% the same as Track_each_session_v16
% only run post-tests (after sample-test trials)

% The experiment paradihm is setting as:
% 
% 1. All reward locations are marked by white door bumpers (0.7inch) at the inner edge of
%    the track.
% 2. In sample trials, a striking marker in a different color (orange) was
%    at reward location besides the corresponding white bumper; but the orange
%    sticker will be removed in the following test trials.
% 3. Sample1(marker)-test1(no marker)-Sample2(marker)-test2(no marker)-
%    Sample3(marker)-test3(no marker)
%    Sample1-20s-test1-40s-sample2-20s-test2........
% 4. 3 mins rest in the animal box in between sessions, and before the
%    first session and after the last session
% 5. A correct/incorrect tone goes off when he stops at correct/incorrect spot.
% 6. In sample trial, rats can stop at other locations besides reward
%    locaiton, and food will be delivered as long as they stop at reward
%    location. However, in test trials, rats are not allowed to stop and
%    turn to the center at the other locations. That means, if rats stop at
%    a wrong location and turn to the center, a incorrect tone will go off
%    and then no food reward will be delivered.
% 7. However, if the rat turned back, criteria are different. If the rat
%    turned back without already passing by the reward location, he still
%    has chance to get the reward; otherwise, he can't get the reward
%    anymore even if he ran back and force around the reward location.
% 8. At the end of each lap, the rat needs to be back to the animal box.
%    This lap (sample or test) will end if he's angle is around 0 degrees,
%    which is the center of the animal box.

% set the missing data [0,0] as the same as the last visited data
