Hey all--For one stimulus, I am randomly calling an image from a text file without replacement ($), and in another stimulus, I am calling an image from a text file completely randomly (%). My question is for data analysis, how can I log which stimulus the computer selected?

The Yoking random pairs (samples\6 v2006\yoking random pairs) output files do not indicate which stimulus was used. This seems like a pretty fundamental question. I hope I haven't missed any documentation.

Thanks.
