Re: Question about BCI2000-OpenBCI: filters.

Hi,

you don't set configuration parameters in source files but in the Operator module's Parameter configuration GUI.
Or you write them into a parameter file and load that at startup.

HTH,

Re: bcı source code building error

I still don't understand why you are getting these errors, but as a workaround you might disable "USE_APPLICATION_BUNDLES" in CMake.
Let me know whether this fixes the problem for you.

Re: Using gusbamp on Windows 10: problem with dll file

Are you actually using BCI2000 version 2? That is quite an outdated version.

Re: bcı source code building error

Maybe the instructions you followed are outdated.
Please follow these instructions:

Re: How to perform a two-dimensional cursor task?

Hi,

running BCI2000/batch/CursorTask_SignalGenerator.bat will provide you with a starting point for 2D feedback.
Duplicate and edit the batch file in order to run your desired signal source module.

HTH,
Jürgen

Re: Question about using OpenBCI for a P3Speller task

Hi,

the buffer duration of 500ms is a limitation of the OpenBCI firmware.
So yes, you would need to modify the firmware if you want to perform P300 experiments using OpenBCI.

Re: sample block duration and StimulusDuration

I cannot reproduce your observations with my current version of BCI2000. If your SampleBlockSize fails to be exactly 200ms long, there might be rounding issues, though.

Re: Setting up a new BCI2000 C++ module - Error

The CMakeLists.txt file in the src/custom directory should not contain a bci2000_add_application_module() statement. Rather, it should only include add_subdirectory() statements. Everything else should go into the CMakeLists.txt file contained inside the src/custom/TEMP directory.

Re: why sample block sice?

If you use a SampleBlockSize of 32, you have 32 samples in a block, not 8. Why this system of sampling? Just like audio data is processed in blocks of data rather than individual samples, so is EEG data. This is because a computer cannot be made to constantly and reliably process data at single samp...
