Event markers

[Tim Campellone]

I was mostly concerned with whether the above E-Prime script would be
enough to mark the data. There is no web support for VPM, and if it
was the case that additional script in that program was needed, I
wanted to start looking immediately. I have seen posts from people
using a variety of software for collecting physio data and was hoping
that maybe a forum member could shed some light on the issue.

Sorry for not checking the E-Prime script prior to posting, but thank
you for your help nonetheless.

Best
Tim
