Designing the multi-stimuli Experiment

[David McFarlane]

Dilip,

I cannot say this enough -- First work through all of the tutorials 
in all of the manuals that come with E-Prime (go completely from 
cover to cover, page to page -- yes, I am serious!).  You will find 
many of your questions already answered there.

Regards,

Stock reminder:  1) I do not work for PST.  2) PST's trained staff 
take any and all questions at https://support.pstnet.com , and they 
strive to respond to all requests in 24-48 hours, so make full use of 
it.  3) In addition, PST offers several instructional videos on their 
YouTube channel (http://www.youtube.com/user/PSTNET ).  4) If you do 
get an answer from PST staff, please extend the courtesy of posting 
their reply back here for the sake of others.
