Hello, I am setting up a mitsar 201 eeg system for doing ERPs studies. We plan to use e-prime (www.pstnet.com) for stimulus presentation. Can anyone give me any suggestions as to how to send synchronization event marks from my stimulus presentation computer to the wineeg computer. I can't seem to get psytask to do it (but I have been told that is becasue i am using winXP and I need win 98!!). Thank you. --Vance MacLaren University of New Brunswick, Canada
