Emotiv amd BCI2000

[Kalvin]

Negative to both - no EPOC software running, and the EPOC does work with its own software. And it is a research edition, of course.

Kalvin,

It would seem that the Emotiv SDK cannot connect to your headset. Is the dongle plugged in and the headset turned on?

Can you give any more specifics about your setup and system? Are you trying to work through a VM?

I'm currently not at the system, but I think that the basic specifications are 1-2GB RAM and a 3Ghz CPU (single core).

[Kalvin]

3.2Ghz Pentium 4
1GB RAm
WinXP Professional SP3

Btw, I installed BCI2000Contrib.exe over the normal installation. Could this be a reason?

[Kalvin]

I just switched to my Thinkpad notebook with a fresh install of the Contrib package, and could run the calibration with the EPOC now.

WinXP Professional SP3
Intel Core 2 Duo P8400 2.26Ghz
3GB RAM (available to XP)


I am currently searching for the reason for this error (after entering the letter Q in the second calibration session) - it might be necessary to change the session run number:

Code: Select all

2011-09-16T10:30:17 - P3SpellerTask::Process: unhandled exception class std::__non_rtti_object (Access violation - no RTTI data!),
terminating Application module.

This error is due to a bug that has been fixed since the last binary distribution came out
(http://www.bci2000.org/tracproj/changeset/3510).

You may avoid the bug by restarting BCI2000 each time you aborted a run, i.e. restart BCI2000 each time after clicking "Suspend" in the Operator module. When a run finishes by itself, no restart is necessary.

Regards,

Ok, thanks!

When I use the BCI2000Launcher I select Signal Source:Emotiv Signal Processing: MatlabSignalProcessing and Application: CursorTask. I get an error
SpatialFiler::Destructor:MatlabFilter::Destructor:Could not load library:libeng:
The specified module could not be found.

I do have Matlab. I have 2010a.

I used the batch file CursorTask_SignalGenerator I changed the code like so
cd ..\prog
start operator.exe ^
--Title %~n0 ^
--OnConnect "-LOAD PARAMETERFILE ..\parms\examples\CursorTask_Emotiv.prm"
start Emotiv.exe 127.0.0.1
start ARSignalProcessing.exe 127.0.0.1
start CursorTask.exe 127.0.0.1
cd ..

I still seem to get the same screen. I changed the parms just as it asked in
http://www.bci2000.org/wiki/index.php/C ... ons:Emotiv

When I go through the cursor task, but when I load the dat file in to BCI2000 offline Analysis I get
Invalid trial change condition specified. I have my Trial change condition as specified here
http://www.bci2000.org/wiki/index.php/U ... hm_Session
If I try and run the sample dat it will run with no issues.



I have been using it for a while. I am running windows vista 32bit. I have spent all day going thru the tutorials and still could not analyze the signals.
Please respond
