The Showplay fMRI software in CIGAL can read streaming eye-position data from the ViewPoint eyetracking program in real-time. When used in this mode, synchronization and generation of eye-position output files is performed automatically for any Showplay paradigm. CIGAL can also be used to send commands to the Viewpoint program to help synchronize the timing of data files generated by Viewpoint (this feature is not yet fully automated).
Note: Initializing communication between the stimulus computer and the eyetracker computer assumes that the appropriate cables between the 2 computers are already connected. This should be the case at the scanner.
The initialize step activates a communication channel between CIGAL and the eyetracker computer. It also sets a flag variable (eye_flag) so that eye-position data will be recorded.
You should not need to do anything else. Eye-position will be automatically recorded for any Showplay tasks you run.
