Like it says in the manual, "you might want the session to skip to a particular block after a fixed time expires--you would enter">300:60000" to tell DirectRT to skip to trial 300 after 60 seconds has elapsed from this point". Here, skipping to trial 300 occurs after the trial with the meta command is executed fully. In the terms of this example, I wanted to skip to trial 300 as soon as the current meta trial exceeds 60 seconds (no matter if it is fully executed or not).
For example, stimuli letters "A", "B", "C" are placed to appear in succession in trial 1, each of which are to be responded by pressing any key. Now, I want to skip to the trial 2 (that displays "what") as soon as 2 seconds elapse (which could be even before letter "C" gets displayed). This will in effect mean skipping mid-trial. So I tried using ">-2:2000" in the meta field which did not work.
Code:
block -trial --meta! bgr wgr style -stim loc time --stim -loc -time --stim ---loc --time
1 ....1 ....>-2:2000 ..0 ..0 ..1 ...~A..0,0,1..rt:any ~B .0,0,1. rt:any..~C ..0,0,1 ..rt:any.*
1.....2....................0...0...1....~what.0,0,1..rt:any..*
(sorry for the cluttered display above)
Can you help?
Thanks
