P300 calibration - text not advancing

Post by rschmaelzle » 14 Jul 2021, 22:29

Hello,
I've been tinkering with the p300 speller via LSL, which worked quite well, except for one critical issue:
The "to be spelled" text is not advancing. For instance, I am trying to spell THE, and the window shows me THE (T), suggesting that I should select the Ts. All is flashing as it should, but it never jumps from the (T) to an (E), which I suppose it should.
I am working with the latest version. However, one peculiarity might be that I am working on a MAC via parallels. However, all is working well, and the LSL crosstalk from Mac (where I am acquiring the EEG) and the virtual Windows10 isn't an issue at all. I see nice signals and all -- the only issue is just the advancing (I am in copy mode and am otherwise following the tutorial as close as I can).
Any ideas are appreciated.
Thanks a ton, Ralf.

Hi,

I don't know which parameters you are using, so I tried the P3Speller_SignalGenerator.bat file, and it works fine for me. Could you try this and maybe double check your parameters?

HTH,
Juergen

I'm having the same issue - have double checked with the signal generator batch file, and the parameters work fine. I'm working directly on Windows 11, not going through any emulators. Double checked that the device is connected, which it is, and that LSL is appropriate, which it should be for ENOBIO8. Does anyone know what is going wrong?

Hi, can you post the contents of the batch file you are using?
Thanks,

There is an error in the batch file. Replace "DummySignalProcessing" with "P3SignalProcessing", and it should work.
