Re: Pupil Diameter and BCI2000

Would it help you if you could specify a state variable as an input to the SpatialFilter?

Re: Pupil Diameter and BCI2000

Hi,

which BCI2000 extension are you using for the TX300? EyetrackerLogger, EyetrackerLoggerTobii3, EyetrackerLoggerTobiiPro, or EyetracerLoggerTobiiX?

Re: How to use VideoPlayer to play video on application window?

Hi,

your VideoPlayer object is destroyed when execution leaves the StartRun() function. You need to create it on the heap (with "new").

Hope this helps,

Re: The error is BCI2000 link to neuroscan

Unfortunately, we don't have a Neuroscan amplifier nor the Scan4.3 software available to test.
We can do remote debugging, if you agree, using Google Remote Desktop. Let us know your location so we can pick a time that is convenient for both of us.

Re: The error is BCI2000 link to neuroscan

Hi,

what do you mean by "latest version"? A download from the BCI2000 website, or did you compile from source?

Re: BCI2000

Hi,

for BCI2000, you need access to the raw EEG. So it seems you should buy the academic licensing option.

Best regards,

Re: Using BCI2000 to combine Python and MATLAB

In principle, this is possible. BCI2000 comes with a MatlabSignalProcessing component that allows you to feed EEG data into a Matlab script, however be aware that the Matlab script needs to be able to process chunks of data in sequence, rather than an entire session as is typically the case. For fur...

Re: No mouse control in SignalGenerator

Alex Belsten just submitted a bug fix. The bug was actually present since r6105.

Thank you for the bug report.

Re: BCI2000 can not see the g.USBamp

It appears that either somehow you are mixing executables from different distributions, or that your distribution is broken.

Have you tried compiling from source?

Re: No mouse control in SignalGenerator

Hi Andrew, sorry for the late reply. Happy new year, as far as it still applies. There was no significant change to the source code of SignalGeneratorADC between r6125 and r6143. The only change was an update to the copyright in the header of the file. Did you accidentally specify a non-empty mixing...

Re: BCI2000 can not see the g.USBamp

Hi, it could be that you have a 32-bit executable and installed 64-bit drivers in the Windows 10 system, whereas in the Windows 7 system you had installed 32-bit drivers. You might try downloading BCI2000 from here: https://www.bci2000.org/mediawiki/index.php/BCI2000_Binaries#August_2020_Version_3.6...

I see. I applied the GetSystemState() fix as well.

Re: embedding the P3 Speller in a Python application

Hi, thanks a lot for sharing this. In the GetStateVariable (self, name) function the return is simply missing. For this you only need to add "return result.value" at the end Straightforward fix, thank you. GetSystemStates () did not correctly return the system state 'Resting', 'Running', 'Suspended'...

Re: embedding the P3 Speller in a Python application

Hi, if you think that there could be some problem with the performance when carrying out the application in this way I don't expect any performance, or timing, problems when embedding the P3Speller window into a different application. The P3Speller remains a separate process, and is able to utilize ...
