As of v2008, there is no auto-import function to adapt ePrime experiments to MediaLab (nor is there one for DirectRT).
It would be a nice feature, but I don't see it happening in the near future, mainly because we're not big ePrime users and so we simply don't know their syntax that well.
If we could find a willing and interested grad student who knows the syntax for each of these programs, maybe it's a project we could start looking into.
