hi  
  
is it possible to know if the calibration, validation or the drift  
correction was good or bad? i mean if nobody is in front of the  
eyelink computer. can i play a sound to know that the calibration (for  
exemple) i have send in front of the experiment computer was good or not?  
thanks.  
  
best
