event marker

I have a text file with words that have a correct response (color word or non-color word). I am using biopac with a stimtracker. I am trying to have a digital pulse sent to acqknowledge via stimtracker for each correct response. I can get the event marker to send a digital signal but not for each correct response. It seems to be random and then it stalls the program.

If you want to send event markers only for a correct response, the best way to do it would be using the Feedback feature. Is this how you implemented your experiment? Do you mind posting your experiment so I can take a look at it? If you do post, please post it as an Experiment Package, which is found under the File menu within SuperLab.
