Trigger event markers from Eprime to BIOPAC

[Catarina Azevedo]

Hi all!

I'm new in eprime and so I realize that this will be a beginner
question.But I really need some help!

I programmed an experiment in which participants will see first a
block of English words and then a block of Dutch words (or the
contrary, order was counterbalanced). The 40 words they will see in
the first block will be chosen pseudo-randomly from a list of 80
words. In the second block they will see their translations. I found a
way to do it with Nested lists (without scripts).

Each participant will see 10 EnglishPositive, 10EnglishNegative, 10
EnglishNeutral, 10English Taboo and 10 DutchPositive, 10DutchNegative,
10 DutchNeutral and 10DutchTaboo words.

I insert a column with the title "marker", being the options 1,2,3,4
for the english words and 5,6,7 and 8 for the dutch words
(corresponding to the type of words).

I would like to know the inline I should write and where so that I
would have 8 different types of events in BIOPAC. I saw this one:

xxx.OnsetSignalEnabled = True
xxx.OnsetSignalPort = &H378
xxx.OnsetSignalData = 1

xxx.OffsetSignalEnabled = True
xxx.OffsetSignalPort = &H378
xxx.OffsetSignalData = 2

But I if I put like this

marker.OnsetSignalEnabled = True
marker.OnsetSignalPort = &H378
marker.OnsetSignalData = 1

marker.OffsetSignalEnabled = True
marker.OffsetSignalPort = &H378
marker.OffsetSignalData = 2

I'm not sure if it will specified the type of words (events) in
Biopac.

Here you have the es. file

Thank you for your attention
