			            Hello, I need a bit of help on how to find response time and average response time. 
 That is, after presenting the stimuli, I would like to know how long time subject took to response and after all stimuli presentations would like know average response time. A small caveat is that if subject do mistakes, I display a message (using /branch) which consumes about 800ms.
 To show average response, I would like not to count the time consumed (due to mistake) into my average response time.
 
 What script I need to add into my trial (may be in /ontrialend?)
 
 Would appreciate any help.
 Thank you in advance.
