Arguments

settings

is a list that could contain: fixation c(x,y,t) where x is one of -20, -6, -3, 0, 3, 6, 20 degrees. y is 0 degrees. t is 0 for a spot fixation marker at c(x,y), or 1 for a square centred on one of (-3,0), (0,0), (+3,0). tracking_on TRUE for tracking on, FALSE for off

Details

Note: tracking will be relative to the PRL established with the fixation marker used at setup (call to OPI-OPEN), so when tracking is on you should use the same fixation location as in the setup.

Value
