Integrating e-prime with fMRI

[David Hairston]

Yes, you can do this quite easily, our lab just started doing it.
If the scanner is set to send/receive a TTL pulse, you can adapt from
the scanner (ours is BNC) into the serial or parallel port of the PC
running E-Prime.  Look up the WritePort command in Help (I think
ReadPort is to take commands in), you basically just give the IRQ
address of the serial port, and it will listen - then have a quick bit
of code set to loop until this comes in, releasing E-prime to continue
w/ the paradigm.

Best of luck,

Dave

Dear all, 

I am new to using e-prime in conjunction with fMRI. How do people go
about this. Ideally I would like e-prime to be triggered by the scanner.
Can one achieve this without IFIS? 

Many thanks in advance for any suggestions. 

With best wishes, 
Daniel
