Setting expInfo details, like participant, is very clear. A default value setting is very clear too. However, I’m curious if there is a way to specify an acceptable range of Ids for running the experiment within builder that would not require coding a verification after startup. There are some reasons why I would not want to add this code after. E-prime has these settings and I’ve found it helpful for certain use cases over the years.
Hello @memlab
The default f"{randint(0, 999999):06.0f}" generates a random number between 0 and 999999 (both included). But there is no check that the participant id has be used before. You might want to consider using the Vespr-Tool https://moryscarter.com/vespr/.
