Thread: Delete intervals between trials.

    Delete intervals between trials.

    Whenever I run my input file in DirectRT, a blank screen/interval is always automatically put in between each trial. When I was creating my file, I did not actually put in an interval. The program is doing this on its own. I need this program to run so that each stimulus shows up immediately (without any intervals) after the previous stimulus is gone.

    I am attaching a small part of my entire input file. Basically, no pink background should show in between the showing of each stimulus. (The response required for the screens with letters on them is either the "s" key or the "d" key.)

    I would appreciate it if someone could help me solve this problem. Thanks a lot for the help!

    Are you talking about the trial interval as described here:

    If so, you can reduce it, but read the section linked above. It's not a good idea to reduce it to 0 because the program needs that time to generate trial events and think a bit.
