I am using two Windows 7 computers; one is labeled "testing" that runs inquisit and one labeled "recording" that runs my EEG recording software, Pycorder (BrainProducts' software).
My issue is I cannot get my EEG stimulus and response markers to appear nor record on Pycorder on the recording computer.
I first tried the default port (LTP1) and the script would not run. I then tried common port addresses and it only runs for COM1.
I have already ruled out with BrainProducts support team that my issue is not with their hardware (also, another researcher in my lab is not having this problem using ePrime software).
I would appreciate any help and input on this matter.
The following is the Inquisit script I am using downloaded from the Millisecond library (Auditory Oddball Task - English; Williams, Simms, Clark, & Paul, 2005) with the port changed from LTP1 to COM1:
# script for sending markers through the port
<port oddballsignal>
/ port = COM1
/ subport = data
/ items = ("00000001")
</port>
<port baselinesignal>
/ port = COM1
/ subport = data
/ items = ("00000010")
</port>
<port responsesignal>
/ port = COM1
/ subport = data
/ items = ("00000011")
</port>
# trial script calling the tone and marker
<trial oddball>
/ skip = [ if (values.lasttrial == trial.oddball.name) values.skipcount += 1 else false ]
/ stimulusframes = [1=oddball,oddballsignal]
/ validresponse = (" ")
/ correctresponse = (" ")
/ responsemessage = (" ", responsesignal, 0)
/ trialduration = 1000
/ posttrialpause = 100
/ ontrialend = [values.lasttrial = trial.oddball.name; values.skipcount = max(values.skipcount - 1, 0);]
</trial>
<trial baseline>
/ stimulusframes = [1=baseline,baselinesignal]
/ validresponse = (" ")
/ correctresponse = (noresponse)
/ responsemessage = (" ", responsesignal, 0)
/ trialduration = 1000
/ posttrialpause = 100
/ branch = [if ( values.skipcount > 0 ) trial.oddball]
/ ontrialend = [values.lasttrial = trial.baseline.name]
</trial>
