Re: does BCI2000 3.0 support two-byte coding in P300 speller

It seems that only four files are relevant for this 3307 change. What do you mean by that? What about the changes to the Operator module in the remaining files? Did you apply them, and did you recompile the Operator module? I would like the parameter setting window to display two-byte symbols corre...

Re: does BCI2000 3.0 support two-byte coding in P300 speller

Thanks Juergen! The update works well. It seems that only four files are relevant for this 3307 change. Localization.cpp StatusBar.cpp TextField.cpp TextWindow.cpp. After the recompiling, the final Application window displays the two-byte symbols correctly, even though the parameter setting window (...

does BCI2000 3.0 support two-byte coding in P300 speller ?

In the version 2.0. We have successfully made P300 Speller read and display the two-byte symbols on the screen. However, the new version 3.0 seems doesn't support the two-byte coding. Any solution for that?

Thanks!

Thank you Adam, for the advice. This is what we have done. We will check whether the training will improve the performance. Hommy Hello, Unfortunately, there is currently no such tool for the sensorimotor rhythm tasks, although something may be in the works. Fortunately, with the motor tasks, you ha...

We are trying to train the Mu Rhythm motor imaginary task with 4 states (left/right hand, both feet, facial movement) with Offline Analysis. Although we have succeeded in training two states's task by manual classifier configuration, the correctness of such configuration is very low for 4 states. Ar...

Dear Juergen, Thank you very much for your reply. We are trying on this following your instruction, and will update the status on this method. Another thing also confuses me in P300Speller. The parameter configuration has a section called "Speller Targets". If I save the target matrix (alphabets) wi...

how to input unicode symbol into the P300 speller

Is there a simple solution to input the unicode or user-defined symbols into P300 speller ? I mean if I change the source code to support the unicode in P3Speller, will that affect the threads of other processing?

Thanks!

Hi, Gery,


Yes, it works!

And the signal is in range only when the electrodes are attached to subjects or in the condition of "in bucket " test. It means the signal should be in a normal testing range to be visible in BCI2000.

Thank you so much!

Hi Gery,

Thank you very much for your reply. I have set the filter with high pass at 0.1Hz or 1 Hz and low pass at 30 Hz.

It doesn't work.

Any other possibilities?

The three modules I used in the BCI2000 launcher are biosemi2.exe, P3SignalProcessing.exe and StimulusPresentation.exe Since...
