Can Eprime work with Neuroscan?

[Richard P. Heitz]

I'm using a neuroscan with E-Prime, and am having a problem with triggers
getting through (I've posted this problem before).  I haven't found any
remedies.  I randomly lose approximately 7% of all triggers.  Leon, if you
end up having this problem too, I'd like to hear about it.

> eprime，hello！
> I am now conducting an ERP study using Neuroscan scanner. I want to
program with Eprime instead of Stim. But I find I can only send a stimuli
onset or offset signal(by OnsetSignalEnabled,OnsetSignalPort,OnsetSignalData
function)  to the scanner and cannot send other signals like response to the
scanner. How can I slove this problem?

Hello,

you can send triggers anytime and anywhere with the "WritePort" command.
Something like this:

WritePort NEUROSCANTRIGGERPORT,ATrigger

Hope this helps
