Hot to make RWG with the constraint of equal numbers of stimuli of each type?

So you want to control the pattern of randomization across subjects? So, e.g., if you have 100 subjects, then 25 will have seen 1a, 25 will have seen 1b, 25 will have seen 1c and 25 will have seen 1d?

Hello, thanks for your response. Yes, that's right, sorry for not mentioning that.

Cheers

Ahh, ok, then the answer is easy--no, there is no way to do that automatically with DirectRT. Each session is independent. Between subject factors need to be dealt with via different input files.

Cheers, sorry for all the fuss
