OSWeb Batch Data session on Jatos
I am about to set up a longitudinal study online. From what I understood, a good way to do this would be to use a Batch Data session in Jatos, and, with some code, manage to extrapolate some relevant data from the first session (i.e., subject ID and condition to which they were assigned) and use this to then assign participants to the correct second session (I will do this in Prolifics).
Unfortunately, though, there are no clear examples on how to work with this Batch Data session with OSweb files. I was wondering whether there is a link you may suggest where this is explained more clearly. What kind of file should I generate to conditionally assign each participant to a certain second session file?
