If you replace the TTL code with a keypress response (e.g., 57 for the spacebar) does that affect the outcome? I'm just curious to know if it's the logic in DirectRT (in general) or if it's specific to TTL input.

the keypress version works instantly it must be a problem with the ttl code part

That is very odd. Can you send me a sample log data file with say 5-10 trials where you respond consistently--say at around 300ms or so? Maybe once via TTL and once via keyboard? I would like to see what is being saved as the display and RT data for those extra images in the TTL version.
