**ShowPlay Reference Manual, Chapter 1 (Introduction): Accuracy**
===== Determining task performance accuracy in real-time =====

To assess accuracy of subject responses during a paradigm you need 3 things:
  * within the parameter file, use the ID code to identify which response would be correct for each trial
  * set the CORRECTCODE variable in the parameter file to use the ID code values
  * run the MAPRESPONSES command during the scan to calibrate which response button means what

This is described in the Showplay manual page for: [[jvs:cigal:showplay:manual:chapter3:correctcode|Correctcode]]
