No output data

[jmicco]

I just finished a trial run of my experiment (a dot-probe task). While the experiment looked exactly as it should, and data files were created by Direct RT, when I opened the data files, no data were recorded.

I attached my the code for the experiment. I'd appreciate any insight re: how to fix this problem-- thanks!

When I open the csv file, it's double spaced and seems to be missing some column data (e.g., like the final STIM values). Maybe this happened through the attachment process. Can you try zipping it and reattaching it if it looks correct on your end?

Hi there,

I reattached the file using Excel, which gets rid of the double-spacing problem. The missing entry for the last stim column is all me. I may have programmed it wrong (this is my first time using the program). Basically, I want the dot probe to disappear after 1500 ms, not necessarily when the subject hits 1 or 9. If I program it such that the time ends with hitting 1 or 9, the probe might be there for more than 1500 ms (for slow responders). So I put in an empty stim column and had that end with a response of 1 or 9. Maybe there is a better way to do it? Could this be why there is no data output? Thanks for your help!

I think I see now. There is a command you can use to clear the screen after a fixed amount of time which waiting for an RT. In your case, I think you could try

RT:1,9,clear1500

You would put that in your last time column (e.g., Column R in your sample) and just get rid of columns S and T.
