Hi,

Using PsychoPy Builder, I’ve created three different experiments which should be presented in a random order for each participant. I’ve tried to upload all of them on PsychoPy Runner and run them in a random order. However, I am not sure I can do the randomization directly from there.  
Has anyone done that before?

Thank you in advance,

PsychoPy doesn’t support that exactly right now, depending on how different the 3 experiments are. Basically, you can’t add a different experiment file onto the Flow (although we’re working on that option right now).

But, what is changing between these experiments? Are the trials structurally very different, or just using different stimuli?
