Viewing Randomly Chosen Stimuli in Output File

Problem solved. I was putting the -1 in a values column, instead of in the BLOCK column.

That solved all the problems.

Ahh, that'll do it. Thanks for the update, glad to hear it worked out. Note to other users--entering a negative value in the Block column (e.g., -1) ensures that data are written for trials that do not collect any RTs--such as "display only" trials.
