[Eeglablist] RE : presentation software

[Andre Achim]

While Presentation and E-Prime include processes to gain very high operating
system priority, in order to insure precise timing, a regular version of
MATLAB clearly does not. I was never confirmed that PsychToolBox includes
such processes; hopefully, it does. A typical ERP applications would likely
yield degraded averages if the time interval between the event pulse and the
actual delivery of the stimulus fluctuates depending on the availability of
the operating system to produce these two event, among other more mundane
tasks that it accomplishes. Preparing stimuli with MATLAB is one thing, but
if someone interpreted your message as meaning that the stimuli could be
delivered in regular MATLAB, it becomes important to warn against doing so.

Dear Robert,
I find Presentation to work well once you get used to the programming
environment. As mentioned, Eprime works well too. However, in the end to
have the most flexibility we have programmed ERP stimuli in Matlab. Sending
triggers to Neuroscan is the same I/O interface as in the other programs,
you just have to send the commands from Matlab.
