Arguments

settings

is a list that could contain: fixation list(x,y,t,c) where x is one of 0, +-2.4, +-4.8 degrees. y is one of 0, +-2.4, +-4.8 degrees. t is 0 for big circle off, 1 for big circle on. p power integer in range 0..1023. bg which is 0 for no background and other for some background tracking which is 0 for no tracking and other for some tracking open If present, will send OPI-OPEN to MAIA and look for prl, onh, fundus image
