  ok, got it. sorry for not searching enough.

  i modified this original tracker:

  http://forum.cogsci.nl/index.php?p=/discussion/351/open-mousetracking-and-visual-world-paradigm/p1

  for my purposes, so to log system time for synchronization as well.
  tracker prepare phase:

  #original scripts from hunterh, see
  #http://forum.cogsci.nl/index.php?p=/discussion/351/open-mousetracking-and-visual-world-paradigm/p1
  
  xList, yList, tList, stList = [], [], [], []
  global xList, yList, tList, stList
  
  global myLog
  
  #initialise sampler
  #from openexp.sampler import sampler
  #src = exp.get_file(self.get("sent") + ".wav")
  #my_sampler = sampler(exp,src)
  #global my_sampler
  

  tracker run phase:

  #original scripts from hunterh, see
  #http://forum.cogsci.nl/index.php?p=/discussion/351/open-mousetracking-and-visual-world-paradigm/p1
  
  #initialise
  start = self.time()
  my_mouse.set_visible()
  
  #initialise logging variables; not necessary, but makes the write command cleaner.
  part = self.get('subject_nr')
  seq = self.get('count_sequence')
  #condition = self.get('cond')
  #snumber = self.get('sent_num')
  
  #set a tracking loop
  tracking = True
  
  while tracking:
      position, timestamp = my_mouse.get_pos()
      x, y = position
      t = timestamp - start
      #system time for synchronization
      st = timestamp
      #uncomment this to print to the debug window.
      #print str(t)+', ' + str(st) + ', ' +str(x)+', '+str(y)
      #write to myLog
      myLog.write(str(x) + ',' + str(y) + ',' + str(t) + ',' + str(st) + ',' + str(seq) + ',' + str(part) + ',' + chr(10))
      #assemble to write trajectories to OS logger (duplicate data and could be removed)
      xList.append(x)
      yList.append(y)
      tList.append(t)
      stList.append(st)
      #set up mouse click
      lclick, mclick, rclick =  get_pressed()
      get()
      #three defined areas, one for each picture
      if x > tr_left and y < tr_below and lclick == 1:
          resp = 1
          mouse_rt = timestamp - start
          print 'Clicked'
          my_canvas.clear()
          tracking = False
          break
      if x > br_left and y > br_above and lclick == 1:
          resp = 2
          mouse_rt = timestamp - start
          print 'Clicked'        
          my_canvas.clear()
          tracking = False
          break
      if x < bl_right and y > bl_above and lclick == 1:
          resp = 3
          print 'Clicked'
          mouse_rt = timestamp - start        
          my_canvas.clear()
          tracking = False
          break
      #This dictates sampling rate. 50 hertz is more than enough
      self.sleep(20)
  my_canvas.clear()
  
  self.experiment.set("Mouse_RT", mouse_rt)
  self.experiment.set("xTrajectory", str(xList))
  self.experiment.set("yTrajectory", str(yList))
  self.experiment.set("tTrajectory", str(tList))
  self.experiment.set("stTrajectory", str(stList))
  self.experiment.set("position", position)
